Graduate studies, commencement 2019.

The Harvard Department of Physics offers students innovative educational and research opportunities with renowned faculty in state-of-the-art facilities, exploring fundamental problems involving physics at all scales. Our primary areas of experimental and theoretical research are atomic and molecular physics, astrophysics and cosmology, biophysics, chemical physics, computational physics, condensed-matter physics, materials science, mathematical physics, particle physics, quantum optics, quantum field theory, quantum information, string theory, and relativity.

Our talented and hardworking students participate in exciting discoveries and cutting-edge inventions such as the ATLAS experiment, which discovered the Higgs boson; building the first 51-cubit quantum computer; measuring entanglement entropy; discovering new phases of matter; and peering into the ‘soft hair’ of black holes.

Our students come from all over the world and from varied educational backgrounds. We are committed to fostering an inclusive environment and attracting the widest possible range of talents.

We have a flexible and highly responsive advising structure for our PhD students that shepherds them through every stage of their education, providing assistance and counseling along the way, helping resolve problems and academic impasses, and making sure that everyone has the most enriching experience possible.The graduate advising team also sponsors alumni talks, panels, and advice sessions to help students along their academic and career paths in physics and beyond, such as “Getting Started in Research,” “Applying to Fellowships,” “Preparing for Qualifying Exams,” “Securing a Post-Doc Position,” and other career events (both academic and industry-related).

We offer many resources, services, and on-site facilities to the physics community, including our electronic instrument design lab and our fabrication machine shop. Our historic Jefferson Laboratory, the first physics laboratory of its kind in the nation and the heart of the physics department, has been redesigned and renovated to facilitate study and collaboration among our students.

Members of the Harvard Physics community participate in initiatives that bring together scientists from institutions across the world and from different fields of inquiry. For example, the Harvard-MIT Center for Ultracold Atoms unites a community of scientists from both institutions to pursue research in the new fields opened up by the creation of ultracold atoms and quantum gases. The Center for Integrated Quantum Materials , a collaboration between Harvard University, Howard University, MIT, and the Museum of Science, Boston, is dedicated to the study of extraordinary new quantum materials that hold promise for transforming signal processing and computation. The Harvard Materials Science and Engineering Center is home to an interdisciplinary group of physicists, chemists, and researchers from the School of Engineering and Applied Sciences working on fundamental questions in materials science and applications such as soft robotics and 3D printing.  The Black Hole Initiative , the first center worldwide to focus on the study of black holes, is an interdisciplinary collaboration between principal investigators from the fields of astronomy, physics, mathematics, and philosophy. The quantitative biology initiative https://quantbio.harvard.edu/  aims to bring together physicists, biologists, engineers, and applied mathematicians to understand life itself. And, most recently, the new program in  Quantum Science and Engineering (QSE) , which lies at the interface of physics, chemistry, and engineering, will admit its first cohort of PhD students in Fall 2022.

We support and encourage interdisciplinary research and simultaneous applications to two departments is permissible. Prospective students may thus wish to apply to the following departments and programs in addition to Physics:

• Department of Astronomy
• Department of Chemistry
• Department of Mathematics
• John A. Paulson School of Engineering and Applied Sciences (SEAS)
• Biophysics Program
• Molecules, Cells and Organisms Program (MCO)

Doctoral Program (Ph.D.)

• Graduate Programs

The Physics Ph.D. program provides students with opportunities to perform independent research in some of the most current and dynamic areas of physics. Students develop a solid and broad physics knowledge base in the first year through the core curriculum, departmental colloquia, and training.

Upper-level courses and departmental seminar series subsequently provide more specialized exposure. Armed with the core knowledge, doctoral students join a research group working in an area of particular interest. This research is performed in very close collaboration with one or more faculty whose interests span a wide range of physics fields.

Applicants are expected to have a strong background in physics or closely related subjects at the undergraduate level. All applications are evaluated holistically to assess the applicant's preparation and potential for graduate coursework and independent research, which can be demonstrated in multiple ways.

Submitting General and Physics GRE scores is recommended (but not required), especially for non-traditional students (this includes applicants with a bachelor's degree outside of physics or applicants who have taken a long gap after completing their bachelor's degree).

Three recommendation letters from faculty or others acquainted with the applicant's academic and/or research qualifications are required.

If you have submitted an application and need to make changes or add to the application, do not send the materials to the Physics department. The department is unable to alter or add to your application. Contact the  Graduate School staff  for all changes.

PhD Program

A PhD degree in Physics is awarded in recognition of significant and novel research contributions, extending the boundaries of our knowledge of the physical universe. Selected applicants are admitted to the PhD program of the UW Department of Physics, not to a specific research group, and are encouraged to explore research opportunities throughout the Department.

Degree Requirements

Typical timeline, advising and mentoring, satisfactory progress, financial support, more information.

Applicants to the doctoral program are expected to have a strong undergraduate preparation in physics, including courses in electromagnetism, classical and quantum mechanics, statistical physics, optics, and mathematical methods of physics. Further study in condensed matter, atomic, and particle and nuclear physics is desirable. Limited deficiencies in core areas may be permissible, but may delay degree completion by as much as a year and are are expected to remedied during the first year of graduate study.

The Graduate Admissions Committee reviews all submitted applications and takes a holistic approach considering all aspects presented in the application materials. Application materials include:

• Resume or curriculum vitae, describing your current position or activities, educational and professional experience, and any honors awarded, special skills, publications or research presentations.
• Statement of purpose, one page describing your academic purpose and goals.
• Personal history statement (optional, two pages max), describing how your personal experiences and background (including family, cultural, or economic aspects) have influenced your intellectual development and interests.
• Three letters of recommendation: submit email addresses for your recommenders at least one month ahead of deadline to allow them sufficient time to respond.
• Transcripts (unofficial), from all prior relevant undergraduate and graduate institutions attended. Admitted applicants must provide official transcripts.
• English language proficiency is required for graduate study at the University of Washington. Applicants whose native language is not English must demonstrate English proficiency. The various options are specified at: https://grad.uw.edu/policies/3-2-graduate-school-english-language-proficiency-requirements/ Official test scores must be sent by ETS directly to the University of Washington (institution code 4854) and be received within two years of the test date.

For additional information see the UW Graduate School Home Page , Understanding the Application Process , and Memo 15 regarding teaching assistant eligibility for non-native English speakers.

The GRE Subject Test in Physics (P-GRE) is optional in our admissions process, and typically plays a relatively minor role.  Our admissions system is holistic, as we use all available information to evaluate each application. If you have taken the P-GRE and feel that providing your score will help address specific gaps or otherwise materially strengthen your application, you are welcome to submit your scores. We emphasize that every application will be given full consideration, regardless of whether or not scores are submitted.

Applications are accepted annually for autumn quarter admissions (only), and must be submitted online. Admission deadline: DECEMBER 15, 2024.

Department standards

Course requirements.

Students must plan a program of study in consultation with their faculty advisor (either first year advisor or later research advisor). To establish adequate breadth and depth of knowledge in the field, PhD students are required to pass a set of core courses, take appropriate advanced courses and special topics offerings related to their research area, attend relevant research seminars as well as the weekly department colloquium, and take at least two additional courses in Physics outside their area of speciality. Seeking broad knowledge in areas of physics outside your own research area is encouraged.

The required core courses are:

In addition, all students holding a teaching assistantship (TA) must complete Phys 501 / 502 / 503 , Tutorials in Teaching Physics.

Regularly offered courses which may, depending on research area and with the approval of the graduate program coordinator, be used to satisfy breadth requirements, include:

• Phys 506 Numerical Methods
• Phys 555 Cosmology & Particle Astrophysics
• Phys 507 Group Theory
• Phys 557 High Energy Physics
• Phys 511 Topics in Contemporary Physics
• Phys 560 Nuclear Theory
• Phys 520 Quantum Information
• Phys 564 General Relativity
• Phys 550 Atomic Physics
• Phys 567 Condensed Matter Physics
• Phys 554 Nuclear Astrophysics
• Phys 570 Quantum Field Theory

Graduate exams

Master's Review:   In addition to passing all core courses, adequate mastery of core material must be demonstrated by passing the Master's Review. This is composed of four Master's Review Exams (MREs) which serve as the final exams in Phys 524 (SM), Phys 514 (EM), Phys 518 (QM), and Phys 505 (CM). The standard for passing each MRE is demonstrated understanding and ability to solve multi-step problems; this judgment is independent of the overall course grade. Acceptable performance on each MRE is expected, but substantial engagement in research allows modestly sub-par performance on one exam to be waived. Students who pass the Master's Review are eligible to receive a Master's degree, provided the Graduate School course credit and grade point average requirements have also been satisfied.

General Exam:   Adequate mastery of material in one's area of research, together with demonstrated progress in research and a viable plan to complete a PhD dissertation, is assessed in the General Exam. This is taken after completing all course requirements, passing the Master's Review, and becoming well established in research. The General Exam consists of an oral presentation followed by an in-depth question period with one's dissertation committee.

Final Oral Exam:   Adequate completion of a PhD dissertation is assessed in the Final Oral, which is a public exam on one's completed dissertation research. The requirement of surmounting a final public oral exam is an ancient tradition for successful completion of a PhD degree.

Graduate school requirements

Common requirements for all doctoral degrees are given in the Graduate School Degree Requirements and Doctoral Degree Policies and Procedures pages. A summary of the key items, accurate as of late 2020, is as follows:

• A minimum of 90 completed credits, of which at least 60 must be completed at the University of Washington. A Master's degree from the UW or another institution in physics, or approved related field of study, may substitute for 30 credits of enrollment.
• At least 18 credits of UW course work at the 500 level completed prior to the General Examination.
• At least 18 numerically graded UW credits of 500 level courses and approved 400 level courses, completed prior to the General Examination.
• At least 60 credits completed prior to scheduling the General Examination. A Master's degree from the UW or another institution may substitute for 30 of these credits.
• A minimum of 27 dissertation (or Physics 800) credits, spread out over a period of at least three quarters, must be completed. At least one of those three quarters must come after passing the General Exam. Except for summer quarters, students are limited to a maximum of 10 dissertation credits per quarter.
• A minimum cumulative grade point average (GPA) of 3.00 must be maintained.
• The General Examination must be successfully completed.
• A thesis dissertation approved by the reading committee and submitted and accepted by the Graduate School.
• The Final Examination must be successfully completed. At least four members of the supervisory committee, including chair and graduate school representative, must be present.
• Registration as a full- or part-time graduate student at the University must be maintained, specifically including the quarter in which the examinations are completed and the quarter in which the degree is conferred. (Part-time means registered for at least 2 credits, but less than 10.)
• All work for the doctoral degree must be completed within ten years. This includes any time spend on leave, as well as time devoted to a Master's degree from the UW or elsewhere (if used to substitute for credits of enrollment).
• Pass the required core courses: Phys 513 , 517 , 524 & 528 autumn quarter, Phys 514 , 518 & 525 winter quarter, and Phys 515 , 519 & 505 spring quarter. When deemed appropriate, with approval of their faculty advisor and graduate program coordinator, students may elect to defer Phys 525 , 515 and/or 519 to the second year in order to take more credits of Phys 600 .
• Sign up for and complete one credit of Phys 600 with a faculty member of choice during winter and spring quarters.
• Pass the Master's Review by the end of spring quarter or, after demonstrating substantial research engagement, by the end of the summer.
• Work to identify one's research area and faculty research advisor. This begins with learning about diverse research areas in Phys 528 in the autumn, followed by Phys 600 independent study with selected faculty members during winter, spring, and summer.
• Pass the Master's Review (if not already done) by taking any deferred core courses or retaking MREs as needed. The Master's Review must be passed before the start of the third year.
• Settle in and become fully established with one's research group and advisor, possibly after doing independent study with multiple faculty members. Switching research areas during the first two years is not uncommon.
• Complete all required courses. Take breadth courses and more advanced graduate courses appropriate for one's area of research.
• Perform research.
• Establish a Supervisory Committee within one year after finding a compatible research advisor who agrees to supervise your dissertation work.
• Take breadth and special topics courses as appropriate.
• Take your General Exam in the third or fourth year of your graduate studies.
• Register for Phys 800 (Doctoral Thesis Research) instead of Phys 600 in the quarters during and after your general exam.
• Take special topics courses as appropriate.
• Perform research. When completion of a substantial body of research is is sight, and with concurrence of your faculty advisor, start writing a thesis dissertation.
• Establish a dissertation reading committee well in advance of scheduling the Final Examination.
• Schedule your Final Examination and submit your PhD dissertation draft to your reading committee at least several weeks before your Final Exam.
• Take your Final Oral Examination.
• After passing your Final Exam, submit your PhD dissertation, as approved by your reading committee, to the Graduate School, normally before the end of the same quarter.

This typical timeline for competing the PhD applies to students entering the program with a solid undergraduate preparation, as described above under Admissions. Variant scenarios are possible with approval of the Graduate Program coordinator. Two such scenarios are the following:

• Students entering with insufficient undergraduate preparation often require more time. It is important to identify this early, and not feel that this reflects on innate abilities or future success. Discussion with one's faculty advisor, during orientation or shortly thereafter, may lead to deferring one or more of the first year required courses and corresponding Master's Review Exams. It can also involve taking selected 300 or 400 level undergraduate physics courses before taking the first year graduate level courses. This must be approved by the Graduate Program coordinator, but should not delay efforts to find a suitable research advisor. The final Master's Review decision still takes place no later than the start of the 3rd year and research engagement is an important component in this decision.
• Entering PhD students with advanced standing, for example with a prior Master's degree in Physics or transferring from another institution after completing one or more years in a Physics PhD program, may often graduate after 3 or 4 years in our program. After discussion with your faculty advisor and with approval of the Graduate Program coordinator, selected required classes may be waived (but typically not the corresponding Master's Review Exams), and credit from other institutions transferred.
• Each entering PhD student is assigned a first year faculty advisor, with whom they meet regularly to discuss course selection, general progress, and advice on research opportunities. The role of a student's primary faculty advisor switches to their research advisor after they become well established in research. Once their doctoral supervisory committee is formed, the entire committee, including a designated faculty mentor (other than the research advisor) is available to provide advice and mentoring.
• The department also has a peer mentoring program, in which first-year students are paired with more senior students who have volunteered as mentors. Peer mentors maintain contact with their first-year mentees throughout the year and aim to ease the transition to graduate study by sharing their experiences and providing support and advice. Quarterly "teas" are held to which all peer mentors and mentees are invited.
• While academic advising is primarily concerned with activities and requirements necessary to make progress toward a degree, mentoring focuses on the human relationships, commitments, and resources that can help a student find success and fulfillment in academic and professional pursuits. While research advisors play an essential role in graduate study, the department considers it inportant for every student to also have available additional individuals who take on an explicit mentoring role.
• Students are expected to meet regularly, at a minimum quarterly, with their faculty advisors (either first year advisor or research advisor).
• Starting in the winter of their first year, students are expected to be enrolled in Phys 600 .
• Every spring all students, together with their advisors, are required to complete an annual activities report.
• The doctoral supervisory committee needs to be established at least by the end of the fourth year.
• The General Exam is expected to take place during the third or fourth year.
• Students and their advisors are expected to aim for not more than 6 years between entry into the Physics PhD program and completion of the PhD. In recent years the median time is close to 6 years.

Absence of satisfactory progress can lead to a hierarchy of actions, as detailed in the Graduate School Memo 16: Academic Performance and Progress , and may jeopardize funding as a teaching assistant.

The Department aims to provide financial support for all full-time PhD students making satisfactory progress, and has been successful in doing so for many years. Most students are supported via a mix teaching assistantships (TAs) and research assistantships (RAs), although there are also various scholarships, fellowships, and awards that provide financial support. Teaching and research assistanships provide a stipend, a tuition waiver, and health insurance benefits. TAs are employed by the University to assist faculty in their teaching activities. Students from non-English-speaking countries must pass English proficiency requirements . RAs are employed by the Department to assist faculty with specified research projects, and are funded through research grants held by faculty members.

Most first-year students are provided full TA support during their first academic year as part of their admission offer. Support beyond the second year is typically in the form of an RA or a TA/RA combination. It is the responsibility of the student to find a research advisor and secure RA support. Students accepting TA or RA positions are required to register as full-time graduate students (a minimum of 10 credits during the academic year, and 2 credits in summer quarter) and devote 20 hours per week to their assistantship duties. Both TAs and RAs are classified as Academic Student Employees (ASE) . These positions are governed by a contract between the UW and the International Union, United Automobile, Aerospace and Agricultural Implement Workers of America (UAW), and its Local Union 4121 (UAW).

Physics PhD students are paid at the "Assistant" level (Teaching Assistant or Research Assistant) upon entry to the program. Students receive a promotion to "Associate I" (Predoctoral Teaching Associate I or Predoctoral Research Associate I) after passing the Master's Review, and a further promotion to "Associate II" (Predoctoral Teaching Associate II or Predoctoral Research Associate II) after passing their General Examination. (Summer quarter courses, and summer quarter TA employment, runs one month shorter than during the academic year. To compendate, summer quarter TA salaries are increased proportionately.)

Ph.D. program

The Applied Physics Department offers a Ph.D. degree program; see  Admissions Overview  for how to apply.  

1.  Courses . Current listings of Applied Physics (and Physics) courses are available via  Explore Courses . Courses are available in Physics and Mathematics to overcome deficiencies, if any, in undergraduate preparation. It is expected the specific course requirements are completed by the  end of the 3rd year  at Stanford.

Required Basic Graduate Courses.   30 units (quarter hours) including:

• Basic graduate courses in advanced mechanics, statistical physics, electrodynamics, quantum mechanics, and an advanced laboratory course. In cases where students feel they have already covered the materials in one of the required basic graduate courses, a petition for waiver of the course may be submitted and is subject to approval by a faculty committee.
• 18 units of advanced coursework in science and/or engineering to fit the particular interests of the individual student. Such courses typically are in Applied Physics, Physics, or Electrical Engineering, but courses may also be taken in other departments, e.g., Biology, Materials Science and Engineering, Mathematics, Chemistry. The purpose of this requirement is to provide training in a specialized field of research and to encourage students to cover material beyond their own special research interests.​

​ Required Additional Courses .  Additional courses needed to meet the minimum residency requirement of 135 units of completed course work. Directed study and research units as well as 1-unit seminar courses can be included. Courses are sometimes given on special topics, and there are several seminars that meet weekly to discuss current research activities at Stanford and elsewhere. All graduate students are encouraged to participate in the special topics courses and seminars. A limited number of courses are offered during the Summer Quarter. Most students stay in residence during the summer and engage in independent study or research programs.

The list of the PhD degree core coursework is listed in the bulletin here:  https://bulletin.stanford.edu/programs/APLPH-PHD .

3.  Dissertation Research.   Research is frequently supervised by an Applied Physics faculty member, but an approved program of research may be supervised by a faculty member from another department.

4.  Research Progress Report.   Students give an oral research progress report to their dissertation reading committee during the winter quarter of the 4th year.

5.  Dissertation.

6.  University Oral Examination .  The examination includes a public seminar in defense of the dissertation and questioning by a faculty committee on the research and related fields.

Most students continue their studies and research during the summer quarter, principally in independent study projects or dissertation research. The length of time required for the completion of the dissertation depends upon the student and upon the dissertation advisor. In addition, the University residency requirement of 135 graded units must be met.

Rotation Program

We offer an optional rotation program for 1st-year Ph.D. students where students may spend one quarter (10 weeks) each in up to three research groups in the first year. This helps students gain research experience and exposure to various labs, fields, and/or projects before determining a permanent group to complete their dissertation work. 

Sponsoring faculty members may be in the Applied Physics department, SLAC, or any other science or engineering department, as long as they are members of the Academic Council (including all tenure-line faculty). Rotations are optional and students may join a group without the rotation system by making an arrangement directly with the faculty advisor. 

During the first year, research assistantships (RAs) are fully funded by the department for the fall quarter; in the winter and spring quarters, RAs are funded 50/50 by the department and the research group hosting the student. RAs after the third quarter are, in general, not subsidized by the rotation program or the department and should be arranged directly by the student with their research advisor.

How to arrange a rotation

Rotation positions in faculty members’ groups are secured by the student by directly contacting and coordinating with faculty some time between the student’s acceptance into the Ph.D. program and the start of the rotation quarter. It is recommended that the student’s fall quarter rotation be finalized no later than Orientation Week before the academic year begins. A rotation with a different faculty member can be arranged for the subsequent quarters at any time. Most students join a permanent lab by the spring quarter of their first year after one or two rotations.  When coordinating a rotation, the student and the sponsoring faculty should discuss expectations for the rotation (e.g. project timeline or deliverables) and the availability of continued funding and permanent positions in the group. It is very important that the student and the faculty advisor have a clear understanding about expectations going forward.

What do current students say about rotations?

Advice from current ap students, setting up a rotation:.

• If you have a specific professor or group in mind, you should contact them as early as possible, as they may have a limited number of rotation spots.
• You can prepare a 1-page CV or resume to send to professors to summarize your research experiences and interest.
• Try to tour the lab/working areas, talk to senior graduate students, or attend group meeting to get a feel for how the group operates.
• If you don't receive a response from a professor, you can send a polite reminder, stop by their office, or contact their administrative assistant. If you receive a negative response, you shouldn't take it personally as rotation availability can depend year-to-year on funding and personnel availability.
• Don't feel limited to subfields that you have prior experience in. Rotations are for learning and for discovering what type of work and work environment suit you best, and you will have several years to develop into a fully-formed researcher!

You and your rotation advisor should coordinate early on about things like: 

• What project will you be working on and who will you be working with?
• What resources (e.g. equipment access and training, coursework) will you need to enable this work?
• How closely will you work with other members of the group? 
• How frequently will you and your rotation advisor meet?
• What other obligations (e.g. coursework, TAing) are you balancing alongside research?
• How will your progress be evaluated?
• Is there funding available to support you and this project beyond the rotation quarter?
• Will the rotation advisor take on new students into the group in the quarter following the rotation?

About a month before the end of the quarter, you should have a conversation with your advisor about things like:

• Will you remain in the current group or will you rotate elsewhere?
• If you choose to rotate elsewhere, does the option remain open to return to the present group later?
• If you choose to rotate elsewhere, will another rotation student be taken on for the same project?
• You don't have to rotate just for the sake of rotating! If you've found a group that suits you well in many aspects, it makes sense to continue your research momentum with that group.

Program Description

Degree Awarded: PHD Physics

The PhD program in physics is intended for highly capable students who have the interest and ability to follow a career in independent research.

The recent advent of the graduate faculty initiative at ASU extends the spectrum of potential physics doctoral topics and advisors to include highly transdisciplinary projects that draw upon:

• biochemistry
• electrical engineering
• materials science
• other related fields

Consequently, students and doctoral advisors can craft novel doctoral projects that transcend the classical palette of physics subjects. Transdisciplinary expertise of this nature is increasingly vital to modern science and technology.

Current areas of particular emphasis within the department include:

• biological physics
• electron diffraction and imaging
• nanoscale and materials physics
• particle physics and astrophysics

The department has more than 90 doctoral students and more than 40 faculty members.

Degree Requirements

Curriculum plan options.

• 84 credit hours, a written comprehensive exam, an oral comprehensive exam, a prospectus and a dissertation

Required Core (18 credit hours) PHY 500 Research Methods (6) PHY 521 Classical and Continuum Mechanics (3) PHY 531 Electrodynamics (3) PHY 541 Statistical Physics (3) PHY 576 Quantum Theory (3)

Electives or Research (54 credit hours)

Culminating Experience (12 credit hours) PHY 799 Dissertation (12)

Additional Curriculum Information Of particular note within the core courses are the PHY 500 Research Methods rotations, which are specifically designed to engage doctoral students in genuine, faculty-guided research starting in their first semester. Students complete three credit hours of PHY 500 in both their fall and spring semesters of their first year, for a total of six credit hours.

Coursework beyond the core courses is established by the student's doctoral advisor and supervisory committee, working in partnership with the student. The intent is to tailor the doctoral training to the specific research interests and aptitudes of the student while ensuring that each graduating student emerges with the expertise, core knowledge and problem-solving skills that define having a successful doctoral degree in physics.

When approved by the student's supervisory committee and the Graduate College, this program allows 30 credit hours from a previously awarded master's degree to be used for this degree. If students do not have a previously awarded master's degree, the 30 credit hours of coursework are made up of electives to reach the required 84 credit hours.

9 things you should consider before embarking on a PhD

June 23, 2021 | 15 min read

By Andy Greenspon

The ideal research program you envision is not what it appears to be

Editor's Note:  When Andy Greenspon wrote this article, he was a first-year student in Applied Physics at Harvard. Now he has completed his PhD. — Alison Bert, June 23, 2021

If you are planning to apply for a PhD program, you're probably getting advice from dozens of students, professors, administrators your parents and the Internet. Sometimes it's hard to know which advice to focus on and what will make the biggest difference in the long-run. So before you go back to daydreaming about the day you accept that Nobel Prize, here are nine things you should give serious thought to. One or more of these tips may save you from anguish and help you make better decisions as you embark on that path to a PhD.

1. Actively seek out information about PhD programs.

Depending on your undergraduate institution, there may be more or less support to guide you in selecting a PhD program – but there is generally much less than when you applied to college.

On the website of my physics department, I found a page written by one of my professors, which listed graduate school options in physics and engineering along with resources to consult. As far as I know, my career center did not send out much information about PhD programs. Only after applying to programs did I find out that my undergraduate website had a link providing general information applicable to most PhD programs. This is the kind of information that is available all over the Internet.

So don't wait for your career center or department to lay out a plan for you. Actively seek it out from your career center counselors, your professors, the Internet — and especially from alumni from your department who are in or graduated from your desired PhD program. First-hand experiences will almost always trump the knowledge you get second-hand.

2. A PhD program is not simply a continuation of your undergraduate program.

Many students don't internalize this idea until they have jumped head-first into a PhD program. The goal is not to complete an assigned set of courses as in an undergraduate program, but to develop significant and original research in your area of expertise. You will have required courses to take, especially if you do not have a master's degree yet, but these are designed merely to compliment your research and provide a broad and deep knowledge base to support you in your research endeavors.

At the end of your PhD program, you will be judged on your research, not on how well you did in your courses. Grades are not critical as long as you maintain the minimum GPA requirement, and you should not spend too much time on courses at the expense of research projects. Graduate courses tend to be designed to allow you to take away what you will find useful to your research more than to drill a rigid set of facts and techniques into your brain.

3. Take a break between your undergraduate education and a PhD program.

You are beginning your senior year of college, and your classmates are asking you if you are applying to graduate school. You think to yourself, "Well, I like studying this topic and the associated research, and I am going to need a PhD if I want to be a professor or do independent research, so I might as well get it done as soon as possible." But are you certain about the type of research you want to do? Do you know where you want to live for the next five years? Are you prepared to stay in an academic environment for nine years straight?

Many people burn out or end up trudging through their PhD program without a thought about what lies outside of or beyond it. A break of a year or two or even more may be necessary to gain perspective. If all you know is an academic environment, how can you compare it to anything else? Many people take a job for five or more years before going back to get their PhD. It is true though that the longer you stay out of school, the harder it is to go back to an academic environment with lower pay and a lack of set work hours. A one-year break will give you six months or so after graduation before PhD applications are due. A two-year gap might be ideal to provide time to identify your priorities in life and explore different areas of research without having school work or a thesis competing for your attention.

Getting research experience outside of a degree program can help focus your interests and give you a leg up on the competition when you finally decide to apply. It can also help you determine whether you will enjoy full-time research or if you might prefer an alternative career path that still incorporates science, for example, in policy, consulting or business — or a hybrid research job that combines scientific and non-scientific skills.

I will be forever grateful that I chose to do research in a non-academic environment for a year between my undergraduate and PhD programs. It gave me the chance to get a feel for doing nothing but research for a full year. Working at the Johns Hopkins University Applied Physics Laboratory in the Space Division, I was the manager of an optics lab, performing spectroscopic experiments on rocks and minerals placed in a vacuum chamber. While my boss determined the overall experimental design, I was able to make my own suggestions for experiments and use my own discretion in how to perform them. I presented this research at two national conferences as well — a first for me. I was also able to learn about other research being performed there, determine which projects excited me the most, and thus narrow down my criteria for a PhD program.

4. Your current area of study does not dictate what you have to study in graduate school.

You might be studying the function and regulation of membrane proteins or doing a computational analysis of the conductivity of different battery designs, but that doesn't mean your PhD project must revolve around similar projects. The transition between college or another research job to a PhD program is one of the main transitions in your life when it is perfectly acceptable to completely change research areas.

If you are doing computation, you may want to switch to lab-based work or vice versa. If you are working in biology but have always had an interest in photonics research, now is the time to try it out. You may find that you love the alternative research and devote your PhD to it, you might hate it and fall back on your previous area of study — or you may even discover a unique topic that incorporates both subjects.

One of the best aspects of the PhD program is that you can make the research your own. Remember, the answer to the question "Why are you doing this research?" should not be "Well, because it's what I've been working on for the past few years already."While my undergraduate research was in atomic physics, I easily transitioned into applied physics and materials science for my PhD program and was able to apply much of what I learned as an undergraduate to my current research. If you are moving from the sciences to a non-STEM field such as social sciences or humanities, this advice can still apply, though the transition is a bit more difficult and more of a permanent commitment.

5. Make sure the PhD program has a variety of research options, and learn about as many research groups as possible in your first year.

Even if you believe you are committed to one research area, you may find that five years of such work is not quite what you expected. As such, you should find a PhD program where the professors are not all working in the same narrowly focused research area. Make sure there are at least three professors working on an array of topics you could imagine yourself working on.

In many graduate programs, you are supposed to pick a research advisor before even starting. But such arrangements often do not work out, and you may be seeking a new advisor before you know it. That's why many programs give students one or two semesters to explore different research areas before choosing a permanent research advisor.

In your first year, you should explore the research of a diverse set of groups. After touring their labs, talking to the students, or sitting in on group meetings, you may find that this group is the right one for you.

In addition, consider the importance of who your research advisor will be. This will be the person you interact with regularly for five straight years and who will have a crucial influence on your research. Do you like their advising style? Does their personality mesh with yours? Can you get along? Of course, the research your advisor works on is critical, but if you have large disagreements at every meeting or do not get helpful advice on how to proceed with your research, you may not be able to succeed. At the very least, you must be able to handle your advisor's management of the lab and advising style if you are going to be productive in your work. The Harvard program I enrolled in has professors working on research spanning from nanophotonics to energy materials and biophysics, covering my wide range of interests. By spending time in labs and offices informally chatting with graduate students, I found an advisor whose personality and research interests meshed very well with me. Their genuine enthusiasm for this advisor and their excitement when talking about their research was the best input I could have received.

6. Location is more important than you think — but name recognition is not.

The first consideration in choosing a PhD program should be, "Is there research at this university that I am passionate about?" After all, you will have to study this topic in detail for four or more years. But when considering the location of a university, your first thought should not be, "I'm going to be in the lab all the time, so what does it matter if I'm by the beach, in a city, or in the middle of nowhere." Contrary to popular belief, you will have a life outside of the lab, and you will have to be able to live with it for four or more years. Unlike when you were an undergraduate, your social and extracurricular life will revolve less around the university community, so the environment of the surrounding area is important. Do you need a city atmosphere to be productive? Or is your ideal location surrounded by forests and mountains or by a beach? Is being close to your family important? Imagine what it will be like living in the area during the times you are not doing research; consider what activities will you do and how often will you want to visit family.

While many of the PhD programs that accepted me had research that truly excited me, the only place I could envision living for five or more years was Boston, as the city I grew up near and whose environment and culture I love, and to be close to my family.

While location is more important than you think, the reputation and prestige of the university is not. In graduate school, the reputation of the individual department you are joining — and sometimes even the specific research group you work in — are more important. There, you will develop research collaborations and professional connections that will be crucial during your program and beyond. When searching for a job after graduation, other scientists will look at your specific department, the people you have worked with and the research you have done.

At the Asgard Irish Pub in Cambridge, Massachusetts, Andy Greenspon talks with fellow graduate students from Harvard and MIT at an Ask for Evidence workshop organized by Sense About Science. He grew up near Boston and chose to go to graduate school there.

7. Those time management skills you developed in college? Develop them further.

After surviving college, you may think you have mastered the ability to squeeze in your coursework, extracurricular activities and even some sleep. In a PhD program, time management reaches a whole new level. You will not only have lectures to attend and homework to do. You will have to make time for your research, which will include spending extended periods of time in the lab, analyzing data, and scheduling time with other students to collaborate on research.

Also, you will most likely have to teach for a number of semesters, and you will want to attend any seminar that may be related to your research or that just peaks your interest. To top it all off, you will still want to do many of those extracurricular activities you did as an undergraduate. While in the abstract, it may seem simple enough to put this all into your calendar and stay organized, you will find quickly enough that the one hour you scheduled for a task might take two or three hours, putting you behind on everything else for the rest of the day or forcing you to cut other planned events. Be prepared for schedules to go awry, and be willing to sacrifice certain activities. For some, this might be sleep; for others, it might be an extracurricular activity or a few seminars they were hoping to attend. In short, don't panic when things don't go according to plan; anticipate possible delays and be ready to adapt.

8. Expect to learn research skills on the fly – or take advantage of the training your department or career center offers.

This may be the first time you will have to write fellowship or grant proposals, write scientific papers, attend conferences, present your research to others, or even peer-review scientific manuscripts. From my experience, very few college students or even PhD students receive formal training on how to perform any of these tasks. Usually people follow by example. But this is not always easy and can be quite aggravating sometimes. So seek out talks or interactive programs offered by your department or career center. The effort will be well worth it when you realize you've become quite adept at quickly and clearly explaining your research to others and at outlining scientific papers and grant proposals. Alternatively, ask a more experienced graduate student or your advisor for advice on these topics. In addition, be prepared for a learning curve when learning all the procedures and processes of the group you end up working in. There may be many new protocols to master, whether they involve synthesizing chemicals, growing bacterial cells, or aligning mirrors on an optical table. In addition, the group may use programming languages or data analysis software you are unfamiliar with. Don't get discouraged but plan to spend extra effort getting used to these procedures and systems. After working with them regularly, they will soon become second nature. When I first started my job at Johns Hopkins, I felt overwhelmed by all the intricacies of the experiment and definitely made a few mistakes, including breaking a number of optical elements. But by the end of my year there, I had written an updated protocol manual for the modifications I had made to the experimental procedures and was the "master" passing on my knowledge to the next person taking the job.

9. There are no real breaks.

In a stereotypical "9-to-5" job, when the workday is over or the weekend arrives, you can generally forget about your work. And a vacation provides an even longer respite. But in a PhD program, your schedule becomes "whenever you find time to get your work done." You might be in the lab during regular work hours or you might be working until 10 p.m. or later to finish an experiment. And the only time you might have available to analyze data might be at 1 a.m. Expect to work during part of the weekend, too. Graduate students do go on vacations but might still have to do some data analysis or a literature search while away.

As a PhD student, it might be hard to stop thinking about the next step in an experiment or that data sitting on your computer or that paper you were meaning to start. While I imagine some students can bifurcate their mind between graduate school life and everything else, that's quite hard for many of us to do. No matter what, my research lies somewhere in the back of my head. In short, your schedule is much more flexible as a PhD student, but as a result, you never truly take a break from your work.

While this may seem like a downer, remember that you should have passion for the research you work on (most of the time), so you should be excited to think up new experiments or different ways to consider that data you have collected. Even when I'm lying in bed about to fall asleep, I am sometimes ruminating about aspects of my experiment I could modify or what information I could do a literature search on to gain new insights. A PhD program is quite the commitment and rarely lives up to expectations – but it is well worth the time and effort you will spend for something that truly excites you.

Requirements for a Doctorate in Physics

An advanced degree in physics at Caltech is contingent upon an extensive research achievement. Students in the program are expected to join a research group, carry out independent research, and write publications for peer-reviewed journals as well as a thesis. The thesis work proposed to a Caltech candidacy committee then presented and evaluated by a Caltech thesis committee in a public defense. Initially, students are required to consolidate their knowledge by taking advanced courses in at least three subfields of physics. Students must also pass a written candidacy exam in both classical physics and quantum mechanics in order to progress into the research phase of the degree.

Graduates of our program are expected to have extensive experience with modern research methods, a broad knowledge of contemporary physics, and the ability to perform as independent researchers at the highest intellectual and technical levels.

The PhD requirements are below and are also available in the Caltech Catalog, Section 4: Information for Graduate Students .

Plan of Study

The plan of study is the set of courses that a student will take to complete the Advance Physics Requirement and any courses needed as preparation to pass the Written Candidacy Exams (see below). Any additional courses the student plans to take as part of their graduate curriculum may be included in the plan of study but are not required. Students should consult with their Academic Advisor on their Plan of Study and discuss any exception or special considerations with the Option Representative. 

Log in to REGIS and navigate to the Ph. D. Candidacy Tab of your Graduate Degree Progress page. Add you courses into the Plan of Study section. When complete, click the "Submit Plan of Study to Option Rep" button. This will generate a notice to the Option Rep to approve your plan of study. Once you complete the courses in the Plan of Study, the Advanced Physics Requirement is completed.

Physics students must demonstrate proficiency in all areas of basic physics, including classical mechanics (including continuum mechanics), electricity and magnetism, quantum mechanics, statistical physics, optics, basic mathematical methods of physics, and the physical origin of everyday phenomena. A solid understanding of these fundamental areas of physics is considered essential, so proficiency will be tested by written candidacy examinations.

No specific course work is required for the basic physics requirement, but some students may benefit from taking several of the basic graduate courses, such as Ph 106 and Ph 125. In addition, the class Ph 201 will provide additional problem solving training that matches the basic physics requirement.

Exam I: Classical Mechanics and Electromagnetism       Topics include: TBA

Exam 2: Quantum Mechanics, Statistical Mechanics and Thermodynamics      Topics include: TBA

Both exams are offered twice each year (July and October) Email  [email protected]  to sign up

Nothing additional. Sign up for the exam by emailing Mika Walton. The Student Programs Office will update your REGIS record once you pass the exams.

Advanced Physics Requirement

Students must establish a broad understanding of modern physics through study in six graduate courses. The courses must be spread over at least three of the following four areas of advanced physics. Many courses in physics and related areas may be allowed to count toward the Advanced Physics requirements.  Below are some popular examples.  Contact the Physics Option Representative to find out if any particular course not listed here can be used for this requirement.

Nothing additional. Once you complete the courses in your approved Plan of Study, the Advanced Physics Requirement is complete.

Oral Candidacy Exam

The Oral Candidacy Exam is primarily a test of the candidate's suitability for research in his or her chosen field. Students should consult with the executive officer to assemble their oral candidacy committee. The chair of the committee should be someone other than the research adviser.

The candidacy committee will examine the student's knowledge of his or her chosen field and will consider the appropriateness and scope of the proposed thesis research during the oral candidacy exam. This exam represents the formal commitment of both student and adviser to a research program.

See also the Physics Candidacy FAQs

After the exam, your committee members will enter their result and any comments they may have. Non-Caltech committee members are instructed to send their results and comments to the physics graduate office who will enter the information on their behalf. Once all "pass" results have been entered, the Option Rep will be prompted to recommend you for admission to candidacy. The recommendation goes to the Dean of Graduate Studies who has the final approval to formally admit you to candidacy.

Teaching Requirement

Thesis advisory committee (tac).

After the oral candidacy exam, students will hold annual meetings with their Thesis Advisory Committee (TAC). The TAC will review the research progress and provide feedback and guidance towards completion of the degree. Students should consult with the executive officer to assemble their oral candidacy committee and TAC by the end of their third year. The TAC is normally constituted from the candidacy examiners, but students may propose variations or changes at any time to the option representative. The TAC chair should be someone other than the research Adviser. The TAC chair will typically also serve as the thesis defense chair, but changes may be made in consultation with the Executive Officer and the Option Rep.

What Is It Like to Do a PhD in Physics?

Physics is arguably the most fundamental scientific discipline and underpins much of our understanding of the universe. Physics is based on experiments and mathematical analysis which aims to investigate the physical laws which make up life as we know it.

Due to the large scope of physics, a PhD project may focus on any of the following subject areas:

• Thermodynamics
• Cosmology and Astrophysics
• Nuclear Physics
• Solid State Physics
• Condensed matter Physics
• Particle Physics
• Quantum mechanics
• Computational Physics
• Theoretical Physics
• Electromagnetism and photonics
• Molecular physics
• And many more

Compared to an undergraduate degree, PhD courses involve original research which, creates new knowledge in a chosen research area. Through this you will develop a detailed understanding of applicable techniques for research, become an expert in your research field, and contribute to extending the boundaries of knowledge.

During your postgraduate study you will be required to produce a dissertation which summarises your novel findings and explains their significance. Postgraduate research students also undertake an oral exam, known as the Viva, where you must defend your thesis to examiners.

To get a better perspective of what life is really like doing a Physics PhD, read the interview profiles below, from those that have been there before, and are there now:

How Long Does It Take to Get a PhD in Physics?

The typical full-time programme has a course length of 3 to 4 years . Most universities also offer part-time study . The typical part-time programme has a course length of 5 to 7 years.

The typical Physics PhD programme sees PhD students study on a probationary basis during their first year. Admission to the second year of study and enrolment onto the PhD programme is subject to a successful first year review. The format of this review varies across organisations but commonly involves a written report of progress made on your research project and an oral examination.

Additional Learning Modules:

Most Physics PhD programme have no formal requirement for students to attend core courses. There are, however, typically several research seminars, technical lectures, journal clubs and other courses held within the Physics department that students are expected to attend.

Research seminars are commonly arranged throughout your programme to support you with different aspects of your study, for example networking with other postgraduates, guidelines on working with your supervisor, how to avoid bias in independent research, tips for thesis writing, and time management skills.

Doctoral training and development workshops are commonly organised both within and outside of the department and aim to develop students’ transferrable skills (for example communication and team working). Information on opportunities for development that exist within the University and explored and your post doctorate career plans will be discussed.

Lectures run by department staff and visiting scholars on particular subject matters relevant to your research topic are sometimes held, and your supervisor (or supervisory committee) is likely to encourage you to attend.

Typical Entry Requirements:

A UK Physics PhD programme normally requires a minimum upper second-class (2:1) honours undergraduate or postgraduate degree (or overseas equivalent) in physics, or a closely related subject. Closely related subjects vary depending on projects, but mathematics and material sciences are common. Graduate students with relevant work experience may also be considered.

Funded PhD programmes (for examples those sponsored by Doctoral Training Partnerships or by the university school) are more competitive, and hence entry requirements tend to be more demanding.

English Language Requirements:

Universities typically expect international students to provide evidence of their English Language ability as part of their applications. This is usually benchmarked by an IELTS exam score of 6.5 (with a minimum score of 6 in each component), a TOEFL (iBT) exam score 92, a CAE and CPE exam score of 176 or another equivalent. The exact score requirements for the different English Language Qualifications may differ across different universities.

Tips to Improve Your Application:

If you are applying to a Physics PhD, you should have a thorough grasp of the fundamentals of physics, and also appreciate the concepts within the focus of your chosen research topic. Whilst you should be able to demonstrate this through either your Bachelors or Master’s degree, it is also beneficial to also be able to show this through extra-curricular engagement, for example attending seminars or conferences. This will also get across your passion for Physics – a valuable addition to your application as supervisors are looking for committed students.

It is advisable to make informal contact with the project supervisors for any positions you are interested in prior to applying formally. This is a good chance for you to understand more about the Physics department and project itself. Contacting the supervisor also allows you to build a rapport, demonstrate your interest, and see if the project and potential supervisor are a good fit for you. Some universities require you to provide additional evidence to support your application. These can include:

• University certificates and transcripts (translated to English if required)
• Academic CV
• Covering Letter
• English certificate – for international students

How Much Does a Physics PhD Degree Typically Cost?

Annual tuition fees for a PhD in Physics in the UK are approximately £4,000 to £5,000 per year for home (UK) students and are around £22,000 per year for overseas students. This, alongside the standard range in tuition fees that you can expect, is summarised below:

Note: The EU students are considered International from the start of the 2021/22 academic year.

Due to the experimental nature of Physics programmes, research students not funded by UK research councils may also be required to pay a bench fee . Bench fees are additional fees to your tuition, which covers the cost of travel, laboratory materials, computing equipment or resources associated with your research. For physics research students in particular this is likely to involve training in specialist software, laboratory administration, material and sample ordering, and computing upkeep.

What Specific Funding Opportunities Are There for A PhD in Physics?

As a PhD applicant, you may be eligible for a loan of up to £25,700. You can apply for a PhD loan if you’re ordinarily resident in the UK or EU, aged 60 or under when the course starts and are not in receipt of Research Council funding.

Research Councils provide funding for research in the UK through competitive schemes. These funding opportunities cover doctoral students’ tuition fees and sometimes include an additional annual maintenance grant. The Engineering and Physical Sciences Research Council (EPSRC) is a government agency that funds scientific research in the UK. Applications for EPSRC funding should be made directly to the EPSRC, but some Universities also advertise EPSRC funded PhD studentships on their website. The main funding body for Physics PhD studentships is EPSRC’s group on postgraduate support and careers, which has responsibility for postgraduate student support.

The Science and Technology Facilities Council (STFC) funds a large range of projects in Physics and Astronomy. To apply for funding students must locate the relevant project, contact the host institution for details of the postdoctoral researcher they wish to approach and then apply directly to them.

You can use DiscoverPhD’s database to search for a PhD studentship in Physics now.

What Specific Skills Will You Get from a PhD in Physics?

PhD doctorates possess highly marketable skills which make them strong candidates for analytical and strategic roles. The following skills in particular make them attractive prospects to employers in research, finance and consulting:

• Strong numerical skills
• Strong analytical skills
• Laboratory experience
• Application of theoretical concepts to real world problems

Aside from this, postgraduate students will also get transferable skills that can be applied to a much wider range of careers. These include:

• Excellent oral and written communication skills
• Great attention to detail
• Collaboration and teamwork
• Independent thinking

What Jobs Can I Get with a PhD in Physics?

The wide range of specialties within Physics courses alone provides a number of job opportunities, from becoming a meteorologist to a material scientist. However, one of the advantages Physics doctorates have over other doctorates is their studies often provide a strong numerical and analytical foundation. This opens a number of career options outside of traditional research roles. Examples of common career paths Physics PostDocs take are listed below:

Academia – A PhD in Physics is a prerequisite for higher education teaching roles in Physics (e.g. University lecturer). Many doctorates opt to teach and supervise students to continue their contribution to research. This is popular among those who favour the scientific nature of their field and wish to pursue theoretical concepts.

PostDoc Researcher – Other postdoctoral researchers enter careers in research, either academic capacity i.e. researching with their University, or in industry i.e. with an independent organisation. Again, this is suited to those who wish to continue learning, enjoy collaboration and working in an interdisciplinary research group, and also offers travel opportunities for international conferences.

Astronomy – Astronomers study the universe and often work with mathematical formulas, computer modelling and theoretical concepts to predict behaviours. A PhD student in this field may work as astrobiologists, planetary geologists or government advisors.

Finance – As mentioned previously, analytical and numerical skills are the backbone of the scientific approach, and the typical postgraduate research programme in Physics is heavily reliant on numeracy. As such, many PostDocs are found to have financial careers. Financial roles typically offer lucrative salaries.

Consulting – Consulting firms often consider a doctoral student with a background in Physics for employment as ideal for consultancy, based on their critical thinking and strategic planning skills.

How Much Can You Earn with A PhD in Physics?

Data from the HESA is presented below which presents the salary band of UK domiciled leaver (2012/13) in full-time paid UK employment with postgraduate qualifications in Physical Studies:

With a doctoral physics degree, your earning potential will mostly depend on your chosen career path.

• How To Apply

The PhD in Physics is a full-time period of research which introduces or builds upon, research skills and specialist knowledge. Students are assigned a research supervisor, a specialist in part or all of the student's chosen research field, and join a research group which might vary in size between a handful to many tens of individuals.

Although the supervisor is responsible for the progress of a student's research programme, the extent to which a postgraduate student is assisted by the supervisor or by other members of the group depends almost entirely on the structure and character of the group concerned. The research field is normally determined at entry, after consideration of the student's interests and the facilities available. The student, however, may work within a given field for a period of time before their personal topic is determined.

There is no requirement made by the University for postgraduate students to attend formal courses or lectures for the PhD. Postgraduate work is largely a matter of independent research and successful postgraduates require a high degree of self-motivation. Nevertheless, lectures and classes may be arranged, and students are expected to attend both seminars (delivered regularly by members of the University and by visiting scholars and industrialists) and external conferences. Postgraduate students are also expected to participate in the undergraduate teaching programme at some time whilst they are based at the Cavendish, in order to develop their teaching, demonstrating, outreach, organisational and person-management skills.

It is expected that postgraduate students will also take advantage of the multiple opportunities available for transferable skills training within the University during their period of research.

Learning Outcomes

By the end of the research programme, students will have demonstrated:

• the creation and interpretation of new knowledge, through original research or other advanced scholarship, of a quality to satisfy peer review, extend the forefront of the discipline, and merit publication;
• a systematic acquisition and understanding of a substantial body of knowledge which is at the forefront of an academic discipline or area of professional practice;
• the general ability to conceptualise, design and implement a project for the generation of new knowledge, applications or understanding at the forefront of the discipline, and to adjust the project design in the light of unforeseen problems;
• a detailed understanding of applicable techniques for research and advanced academic enquiry; and
• the development of a PhD thesis for examination that they can defend in an oral examination and, if successful, graduate with a PhD.

The Postgraduate Virtual Open Day usually takes place at the end of October. It’s a great opportunity to ask questions to admissions staff and academics, explore the Colleges virtually, and to find out more about courses, the application process and funding opportunities. Visit the  Postgraduate Open Day  page for more details.

PhD in Physics (3+ years)

The majority of postgraduate students (about 110 are accepted each year) carry out research at the Cavendish Laboratory towards a PhD degree.

For admission to the PhD, the Postgraduate Admissions Office normally requires applicants to have achieved the equivalent of a UK Masters (Pass) . Applicants should obtain the equivalent of:

• at least a 2:i in a UK four-year "undergraduate Master's" (Honours) degree,  OR
• at least a 2:i in a UK three-year Bachelor's (Honours) degree plus a relevant one/two -year UK Master's degree.

All applicants are assessed individually on the basis of their academic records.

Full-time students must spend at least three terms of residence in Cambridge and nine terms of research. If you are undertaking a placement or internship away from Cambridge for more than two weeks you need to apply for leave to work away.

Final examination involves the submission of a thesis of not more than 60,000 words followed by an oral examination (or viva) of the thesis and the general field of physics into which it falls.

Successful applicants are assigned to a research supervisor, a specialist in part or all of the student's chosen research field, and joins a research group which might vary in size between 4 and 80 individuals. Although the supervisor is responsible for the progress of a student's research programme, the extent to which a postgraduate student is assisted by the supervisor or by other members of the group depends almost entirely on the structure and character of the group concerned. The research field is normally determined at entry, after consideration of the student's interests and facilities available.

A list of current research projects is published and available on the  research pages  of our website, and more detailed information about specific research areas can be obtained from the relevant academic staff. The student, however, may work within a given field for a period of time before his or her personal topic is determined.

There is no requirement by the University of attendance at formal courses of lectures for the PhD. Postgraduate work is largely a matter of independent research and successful postgraduates require a high degree of self-motivation. Nevertheless, lectures and classes may be arranged, and students are expected to attend both seminars (delivered regularly by members of the University and by visiting scholars and industrialists) and external conferences. In addition, postgraduate students carry out first- and second-year physics undergraduate supervision and assist with practical work and theoretical examples classes in the Department.

Lectures within all the faculties of the University are open to any member of the University, and a physics postgraduate student has the opportunity of attending lectures not only within the undergraduate Physics and Theoretical Physics course, but also in any other subject area or faculty.

Purdue physicists throw world’s smallest disco party

A new milestone has been set for levitated optomechanics as prof. tongcang li’s group observed the berry phase of electron spins in nano-sized diamonds levitated in vacuum.

Physicists at Purdue are throwing the world’s smallest disco party.  The disco ball itself is a fluorescent nanodiamond, which they have levitated and spun at incredibly high speeds. The fluorescent diamond emits and scatters multicolor lights in different directions as it rotates. The party continues as they study the effects of fast rotation on the spin qubits within their system and are able to observe the Berry phase. The team, led by Tongcang Li , professor of  Physics and Astronomy  and  Electrical and Computer Engineering at Purdue University, published their results in Nature Communications . Reviewers of the publication described this work as “arguably a groundbreaking moment for the study of rotating quantum systems and levitodynamics” and “a new milestone for the levitated optomechanics community.”

“Imagine tiny diamonds floating in an empty space or vacuum. Inside these diamonds, there are spin qubits that scientists can use to make precise measurements and explore the mysterious relationship between quantum mechanics and gravity,” explains Li, who is also a member of the Purdue Quantum Science and Engineering Institute .  “In the past, experiments with these floating diamonds had trouble in preventing their loss in vacuum and reading out the spin qubits. However, in our work, we successfully levitated a diamond in a high vacuum using a special ion trap. For the first time, we could observe and control the behavior of the spin qubits inside the levitated diamond in high vacuum.”

The team made the diamonds rotate incredibly fast—up to 1.2 billion times per minute! By doing this, they were able to observe how the rotation affected the spin qubits in a unique way known as the Berry phase.

“This breakthrough helps us better understand and study the fascinating world of quantum physics,” he says.

The fluorescent nanodiamonds, with an average diameter of about 750 nm, were produced through high-pressure, high-temperature synthesis. These diamonds were irradiated with high-energy electrons to create nitrogen-vacancy color centers, which host electron spin qubits. When illuminated by a green laser, they emitted red light, which was used to read out their electron spin states. An additional infrared laser was shone at the levitated nanodiamond to monitor its rotation. Like a disco ball, as the nanodiamond rotated, the direction of the scattered infrared light changed, carrying the rotation information of the nanodiamond.

The authors of this paper were mostly from Purdue University and are members of Li’s research group: Yuanbin Jin (postdoc), Kunhong Shen (PhD student), Xingyu Gao (PhD student) and Peng Ju (recent PhD graduate). Li, Jin, Shen, and Ju conceived and designed the project and Jin and Shen built the setup. Jin subsequently performed measurements and calculations and the team collectively discussed the results. Two non-Purdue authors are Alejandro Grine, principal member of technical staff at Sandia National Laboratories, and Chong Zu, assistant professor at Washington University in St. Louis. Li’s team discussed the experiment results with Grine and Zu who provided suggestions for improvement of the experiment and manuscript.

“For the design of our integrated surface ion trap,” explains Jin, “we used a commercial software, COMSOL Multiphysics, to perform 3D simulations. We calculate the trapping position and the microwave transmittance using different parameters to optimize the design. We added extra electrodes to conveniently control the motion of a levitated diamond. And for fabrication, the surface ion trap is fabricated on a sapphire wafer using photolithography. A 300-nm-thick gold layer is deposited on the sapphire wafer to create the electrodes of the surface ion trap.”

So which way are the diamonds spinning and can they be speed or direction manipulated? Shen says yes, they can adjust the spin direction and levitation.

“We can adjust the driving voltage to change the spinning direction,” he explains. “The levitated diamond can rotate around the z-axis (which is perpendicular to the surface of the ion trap), shown in the schematic, either clockwise or counterclockwise, depending on our driving signal. If we don’t apply the driving signal, the diamond will spin omnidirectionally, like a ball of yarn.”

Levitated nanodiamonds with embedded spin qubits have been proposed for precision measurements and creating large quantum superpositions to test the limit of quantum mechanics and the quantum nature of gravity.

“General relativity and quantum mechanics are two of the most important scientific breakthroughs in the 20 th century. However, we still do not know how gravity might be quantized,” says Li. “Achieving the ability to study quantum gravity experimentally would be a tremendous breakthrough. In addition, rotating diamonds with embedded spin qubits provide a platform to study the coupling between mechanical motion and quantum spins.”

This discovery could have a ripple effect in industrial applications. Li says that levitated micro and nano-scale particles in vacuum can serve as excellent accelerometers and electric field sensors. For example, the US Air Force Research Laboratory (AFRL) are using optically-levitated nanoparticles to develop solutions for critical problems in navigation and communication .

“At Purdue University, we have state-of-the-art facilities for our research in levitated optomechanics,” says Li. “We have two specialized, home-built systems dedicated to this area of study. Additionally, we have access to the shared facilities at the Birck Nanotechnology Center, which enables us to fabricate and characterize the integrated surface ion trap on campus. We are also fortunate to have talented students and postdocs capable of conducting cutting-edge research. Furthermore, my group has been working in this field for ten years, and our extensive experience has allowed us to make rapid progress.”

Quantum research is one of four key pillars of the   Purdue Computes   initiative, which emphasizes the university’s extensive technological and computational environment.

This research was supported by the National Science Foundation (grant number PHY-2110591), the Office of Naval Research (grant number N00014-18-1-2371), and the Gordon and Betty Moore Foundation (grant DOI 10.37807/gbmf12259). The project is also partially supported by the Laboratory Directed Research and Development program at Sandia National Laboratories.
