Johns Hopkins is the nation’s first research university. That emphasis on research continues to this day and forms the backbone of the undergraduate and graduate programs in the Department of Physics and Astronomy. The department’s research program is focused into four areas of excellence:

• Astrophysics
• Condensed Matter Physics
• Elementary Particle Physics
• Plasma Physics

For graduate students interested in these fields, the department offers world-class research opportunities in a friendly and supportive setting. For undergraduates, JHU offers exposure to cutting-edge research combined with a level of personal attention that is typically found only in liberal arts colleges. Nearly all physics majors at JHU work on research projects and many begin as freshmen or sophomores.

All research builds upon an established body of knowledge. To be effective researchers, teachers, or professionals, both undergraduate and graduate students must acquire a core knowledge of physics. Our undergraduate and graduate courses are designed to cover the core subjects at the appropriate levels, leading to advanced courses on a variety of specialized topics. As a consequence, students having different backgrounds or different ultimate objectives can select those parts that are most appropriate for them. The selections are made under the guidance of a faculty advisor. The advisor aids the student in making the most efficient use of their time and ensures that their program contains a reasonable balance among classroom and laboratory, mathematics, seminars, and introduction to research.

Donald E. Kerr Memorial Prize

In recognition of Dr. Kerr’s work in microwave physics, the department awards the Donald E. Kerr Memorial Prize each year to the most outstanding undergraduate major graduating in physics.

The Department of Physics and Astronomy’s first facility was Rowland’s measuring engine for determining the solar spectrum in the 1880s. Ever since that time the Department has maintained a long and continuous history in instrumentation. In recent decades this has extended to instrumentation for space missions. The Department maintains a Class-1000 clean room for microfabrication and nanofabrication, a high bay lab, professional and student machine shops, and supports a world-renowned Instrument Development Group (IDG) with six full-time engineers and three full-time machinists.

Among the diverse techniques used for studying condensed matter physics are magnetometry/susceptometry, specific heat and transport measurements, atomic force and magnetic force microscopy, X-ray and electron diffraction, terahertz spectroscopy, and neutron scattering at the nearby NIST Center for Neutron Research and at the Spallation Neutron Source, ORNL. A variety of cryostats, He3 refrigerators, and He3-He4 dilution refrigerators together with high temperature ovens, electromagnets, and superconducting magnets allow measurements to be made from 0.05 K to 1100 K and in magnetic fields up to 14 Tesla. Apparatus for the preparation of samples includes two image furnaces for floating zone growth, single-crystal growth vacuum furnaces, box and tube furnaces, arc furnaces, several high vacuum and ultra-high vacuum chambers for thin film fabrication using evaporation, MBE, pulsed laser deposition, sputtering, and focused ion beam (FIB) milling. Also available on campus are cutting-edge transmission electron microscopes and scanning electron microscopes.

In astrophysics, research groups have state-of-the-art laboratories for testing cryogenic transition-edge bolometer detectors with SQUID read-out electronics, and closed-cycle helium crogenics. Recent instrumentation advances include the design and manufacture of large free-standing polarization grids and novel high-bandwidth smooth-wall feed horns. Current activities include development of microwave and millimeter-wave instruments for far-infrared and microwave astronomy and cosmology.

The research groups in the department have a wide range of state-of-the-art computer facilities including high performance clusters with over a thousand processors and the largest database at a university—over a petabyte. All undergraduate majors and graduate students have access to high performance workstations.

Financial Aid

Graduate students in good standing are normally supported by a combination of fellowships, research assistantships and teaching assistantships. The financial package covers full tuition, individual health insurance, and an academic year salary commensurate with that of other leading research institutions. Teaching assistantship is a common mode of financial support; experience in teaching is a valuable part of the Ph.D. program. A teaching assistantship supports the student during the academic year and is supplemented by a research assistantship during the summer. The assistant is expected to help in the teaching of the general physics course and other introductory and major courses. The typical teaching duties include leading a problem-solving section or laboratory exercises and homework grading. Research assistantships are based on the availability of funding to the research advisor and are arranged directly with them. Research assistantships provide an opportunity for deep engagement in ongoing experimental or theoretical research. In addition, the department and the University offer several fellowships on a competitive basis, some covering travel, supplies or research expenses and some covering a semester’s or a year’s worth of the entire financial package. Some students are supported by external fellowships, such as the pre-doctoral fellowship of the National Science Foundation.

All fellows and teaching and research assistants in the Department of Physics and Astronomy register as full-time students and thus fulfill their residence requirements while holding appointments. Loans and work-study arrangements are available from the Office of Financial Aid.

Graduate Programs

Graduate study in physics and astronomy at JHU is intended primarily to prepare Ph.D. graduates for careers in teaching and research in physics and astronomy, or in applications such as biophysics, space physics, and industrial research. Entering students may elect to work toward a Ph.D. in physics or a Ph.D. in astronomy and astrophysics. The two programs are similar in structure but have somewhat different course requirements (see the programs tab). A wide range of research projects—both theoretical and experimental—are available for graduate students in Astrophysics , Condensed Matter Physics , Particle Physics , and Plasma Spectroscopy.

We all know that the energy we use on a daily basis can come from a variety of sources, but a discussion of the merits and drawbacks to those sources more often leads to political argument than fact-based scientific dialogue. This course, meant for science and non-science students alike, explores the principles behind how energy from fossil fuels, solar, wind, nuclear, and other resources is produced, how efficiently the energy can be harnessed, and what effect the process has and will have on our environment and society today and in the future. Students will apply this fundamental understanding to compare and understand how each source could be used in real world scenarios. Ultimately, the course is intended to help students use a scientific perspective to shape their opinions when faced with these controversial topics.

This course offers a broad overview of the fundamental ideas of modern physics: mechanics, space, time, relativity, quantum mechanics, and quantum field theory, up to general relativity and the Standard Model of particle physics. The course will be descriptive but equation-based, including explicit details about the foundational equations of the theories discussed. The goal will be to understand the meaning of those equations and the concepts they represent, rather than to gain facility in manipulating and solving the equations. This course is aimed at non-physics majors

A background in quantum mechanics and quantum field theory is recommended for the course.

General Relativity predicts its own demise in the existence of singular black hole solutions. There have been mounting astrophysical evidence that black holes do exist in nature. Thus they are not just pathologies of the theory but fundamental objects in gravity that require understanding. Theoretically, they serve as "laboratories" for studies in quantum gravity; indeed, most of the research in the field aims to resolve various paradoxes and puzzles that emerge when one tries to understand physics inside or outside black holes. The goal of this course is to elucidate these paradoxes and puzzles. First, we will study the classical properties of black holes in general relativity such as horizons, causal history, singularity theorems, area theorems and black hole mining. Next, we will study semi-quantum and quantum properties such as black hole thermodynamics, Hawking radiation, black hole evaporation. We will also explore modern results and perspectives on the fundamental physics of black holes that are necessary for current research. A background in general relativity and quantum field theory is recommended for the course.

The overwhelming evidence that dark matter exists and that it is not part of the fundamental theory of matter (the standard model) suggests the need for a graduate course. I will cover what is known and not known about dark matter, being specific enough to open lines of inquiry. I will cover what the rules of quantum field theory would allow it to be and how it could interact with us. I will go over possible mechanisms that explain the generation of dark matter in our universe in the first place. In addition, I will go over the ways to potentially discover (interact with) it directly.The first half or more of the course should be mostly accessible to advanced graduate students in astrophysics and high-energy particle experimentalists. The last half/third will be more field-theory oriented

Cross Listed Courses

An advanced introduction to turbulence theory for graduate students in the physical sciences, engineering and mathematics. Both intuitive understanding and exact analysis of the fluid equations will be stressed. Previous familiarity with fluid mechanics is not required, although it could be helpful.

Most physicists and cosmologists still dream of a final theory for the cosmos, the one-inch mathematical formula that will explain... everything. From atoms to galaxies, from morals to daydreams. Is this possible? Can a single theory account for everything we see? Some physicists, such as Don Lincoln and Steven Weinberg believe so. Others, such as Lisa Randall and Carlo Rovelli are skeptical.In this course we will examine arguments for and against the existence of an all-encompassing theory from the point of view of philosophy and cosmology. We will read from a wide variety of sources, including popular science books, scientific articles, and classical texts in the philosophy of science. We will also trace the intellectual history of the notion of an all-encompassing theory in Western philosophy and in physics.

Distribution Area: Humanities

In this First-Year Seminar, we will seek to answer questions including: could you forge Beskar? What would it take to make a light saber? Is "Image, enhance" really possible? What is possible today? What might be possible in the future? And, what may never be possible, as it violates the laws of nature as we know them? We will take an empiricist approach, gathering data on the needed properties via screenings and related research, and then applying physical principles to reveal feasibility.

Science and scientists often bear the brunt of public displeasure over current events. Recent debates over CoVID (the safety and effectiveness of vaccines, masks, and isolation), climate change, and many other controversies raise questions about the reliability of scientific results and what it means to conduct research. What is and what is not scientific? How can non-scientists determine whether a scientific result is "right?" In this First-Year Seminar, we will explore what scientists do -- the practices of science -- and how they set standards of knowledge. Discussions will be organized around current pressing topics, including: What does it mean to "follow the science" or "do your own research" in the age of COVID? Will science save us from the ravages of climate change? Who or what has ultimate authority over the direction of scientific advances? When are new scientific announcements important new results and when are they just click bait hype? Who pays for science and should we care? What is meant by replication and is it bad if it doesn't happen? How does scientific publication work and what issues have arisen? Why do scientists often get bad press, and is it fair?

This First-Year Seminar considers what we can learn about democratic societies by thinking of them as complex physical systems. We will discuss voting and social choice theories and their relationship to renormalization and emergence; organization and segregation in complex systems: power laws, inequality, and polarization; and the dynamics of information and opinions: networks, bubbles, filters, and phase transitions.

Distribution Area: Humanities, Natural Sciences

This First-Year Seminar will explore how some important results in physics and astronomy are discovered, their transformative implications to the basic understanding of nature and their impact on the progress of society. Students will explore how simple rules obtained from the lab or in idealized settings imply the complex behaviors and dynamics observed in the natural world, and how they back-reaction on society. The seminar will explore the motivations for doing scientific research in various context, and how they relate to the application of scientific discoveries. An example of topic that will be explored is General Relativity, a subject that emerged purely from theoretical considerations by Einstein which have revolutionized our basic understanding of the physical world and have reshaped the fields of physics and astronomy. On the other hand, General Relativity is necessary for satellite timing which revolutionized communication in human society. Another example is the basic physics experiments and research that lead to the invention of the transistor and the ensuing revolution of the information age. The students will explore the value of scientific thinking and its necessity in building a more robust society that can effectively serve its citizens. We will have regular visits and talks from leading researchers throughout the Hopkins ecosphere. This will help guide the in-class discussions.

This First-year Seminar will study the direction of time, pointing from past to future. It will primarily be based on the physics of entropy and the Second Law of Thermodynamics, covering aspects of statistical mechanics, probability, and cosmology. But it will also touch on how time's arrow manifests itself in the macroscopic world, including questions of memory, prediction, aging, and causality.

This First-Year Seminar combines current state of the art issues in Cosmology, Astrophysics and Biology around the Scientific American level. Discusses the history of thought on these issues ranging from Aristotle, Lucretius, Galileo, Newton, Einstein…to the Hubble and JWST era. For the last part of the seminar, we will consider existential issues for humanity in our Universe. Excellent books to read to start thinking about this are by Toby Ord: Precipice and Martin Rees: (1) The Future of Humanity and (2) If Science is to Save us. Our discussions and investigations will likely lead us toward many interesting and innovative paths.

This multidisciplinary course explores the origins of life, planet formation, Earth's evolution, extrasolar planets, habitable zones, life in extreme environments, the search for life in the Universe, space missions, and planetary protection. Recommended Course Background: Three upper level (300+) courses in sciences (Biophysics, Biology, Chemistry, Physics, Astronomy, Math, or Computer Science).

Prerequisite(s): Students may not register for this class if they have already received credit for AS.020.334 OR AS.020.616 OR AS.171.333 OR AS.171.699 OR AS 270.335 OR AS.360.671

Prerequisite(s): Students may not register for this class if they have already received credit for AS.020.616 OR AS.020.334 OR AS.171.333 OR AS.171.699 OR AS.270.335 OR AS.360.339 .

This course will consider some philosophical topics in the foundations of physics. Entropy and the arrow of time -- why time has a direction, whether it can be explained in terms of entropy, and what role the arrow of time plays in causation and emergence. Anthropics and indexical uncertainty -- approaches to probability, reference classes, the cosmological multiverse, Boltzmann brains, simulation and doomsday arguments. Foundations of quantum mechanics -- the measurement problem, many-worlds, probability and structure, alternative approaches.

From the director.

Dear prospective applicant,

We have designed the curriculum with three complementary objectives in mind. First, to make your two years in this program as rewarding as possible in terms of your short and long-term career objectives. Second to introduce you to other areas of Medical Physics that you may find interesting and third to highlight for you the tremendous value that medical physicists can bring to medical research endeavors beyond the role of a clinical medical physicist. As program director, I see it my responsibility to help every program participant meet and, ideally exceed, their own definition of career success. The unparalleled resources and opportunities available within the broader Hopkins community make this possible. For those interested in a clinical therapy physics position, we already have a residency program in therapy physics within The Radiation Oncology Department to which master’s graduates may apply. We will also provide the opportunity to train in the emerging and highly multidisciplinary area of theranostic physics and radiopharmaceutical dosimetry. This relatively new area requires individuals that are familiar with both therapeutic and diagnostic physics as well as the physics aspects related to the use of radiopharmaceuticals for therapy, in particular pharmacokinetic modeling and dosimetry. This is a growth area and one that is in need of medical physics expertise – in the clinic, in industry and in academia.
