The Department of Physics offers programs of study leading to the Master of Science (MS) and Doctor of Philosophy (PhD) degrees. The department is strongly committed to graduate education and supports it by maintaining a strong, well-funded, and diverse research program.

A basic goal of the program of graduate education is to prepare students for careers in research and related fields. It is intended that graduates will have the education and training necessary to enable them to make fundamental contributions to knowledge in physics or their chosen field. Further, it is anticipated that they will be peers with the next generation of technology leaders in industry, government, and academia.

The faculty believes that the quality of teaching, at all levels, is enhanced by a strong research program. Undergraduates, graduate students, and post-doctoral fellows participate in all aspects of research in physics at Florida State University. In fact, most undergraduate physics majors participate in research projects and many are co-authors on publications. This research includes strong programs in the area of computational physics and both experimental and theoretical studies in high energy, nuclear, condensed matter, astrophysics, and atomic and molecular physics. There are also many opportunities for interdisciplinary research, particularly in the Integrative NanoScience Institute (INSI), the National High Magnetic Field Laboratory (NHMFL), the Department of Scientific Computing, and the Institute of Molecular Biophysics (IMB).

Available experimental facilities include the following: a 9.5 MV Super FN Tandem Van de Graaff accelerator with superconducting post accelerator, the RESOLUT radioactive beam facility, a state-of-the-art gamma spectroscopy array, electron spin resonance and electron double nuclear resonance spectrometers, a detector development laboratory for high-energy particle detectors, liquid helium refrigerators, thin film preparation facilities including sputtering and laser ablation, ultrahigh vacuum instrumentation including surface analysis (LEED, Auger, optical) and molecular beam epitaxy, synthesis and characterization facilities for novel materials, three X-ray diffractomers with various sample stages for high and low temperature studies, multi-sample analysis and small angle studies, scanning electron, tunneling and optical microscopies with image analysis, SQUID and vibrating sample magnetometers, and a helium atom surface scattering facility. The NHMFL provides a modern infrastructure enabling research in magnetic fields including the highest powered DC fields in the world, mainly used for materials science research, and facilities providing the highest fields in the world for nuclear, ion cyclotron and electron magnetic resonance spectometers as well as magnetic resonance imaging.

Computational resources are an integral part of scientific research in the department and play an increasingly important role in preparing students for careers in both commercial and academic fields. Recent advances in data acquisition, algorithm development, and computer hardware have made high performance computing fundamentally necessary to remain competitive. The Physics Department has been actively involved in high performance computing for many years. Researchers in the department are responsible for the design, acquisition, installation, and operations of many computing clusters with an aggregate of over 1000 CPUs and over 100 terabytes of disk storage. The University has acquired a wide array of computing facilities to meet its research needs and maintains an ambitious plan to continually upgrade current shared supercomputing facilities. Since 1993, FSU has maintained high performance computing facilities on campus, which have consistently put the University on the “Top 500 Supercomputer” site (http://www.top500.org). The shared-HPC facility is capable of over thirty-eight TFLOPS. The system consists of over 3800 CPU cores. Inter-process communication runs over an Infiniband network. All compute and log in nodes have access to a 190 TByte Panasas high performance parallel Object Storage Device. The HPC general access network infrastructure is connected to FSU’s ten-Gbps campus network backbone and to the ten-Gbps Florida Lambda Rail.

## Requirements

Please review all college-wide degree requirements summarized in “College of Arts and Sciences” chapter of this *Graduate Bulletin*. The physics department also has a *Guide to Graduate Studies in Physics at Florida State University**.* This booklet is about twenty-five pages in length and contains all the requirements and advice to students studying graduate physics.

For the **master’s** degree a student must take at least three of the above core courses, including at least one course in quantum mechanics. For the **doctoral**** **degree, the student is required to also take either: PHY 5667, Quantum Field Theory; or PHY 5670, Quantum Many-Body Physics. After attaining mastery of the content of the core graduate courses, a PhD student is required to take two of the following six courses: PHZ 5305, Nuclear Physics I; PHZ 5315, Nuclear Astrophysics; PHZ 5354, High Energy Physics I; PHZ 5491, Condensed Matter Physics I; or PHZ 5715, Biophysics I. In addition, the student is required to complete one more course from the following set: AST 5245, Radiative Processes in Astronomy; PHZ 5307, Nuclear Physics II; PHZ 5355, High Energy Physics II; PHZ 5492, Condensed Matter Physics II; PHZ 5669, Quantum Field Theory B; or PHZ 5716, Biophysics II, and at least one of the following courses: AST 5765, Advanced Analysis Techniques in Astronomy; AST 5760, Computational Astrophysics; PHY 5669, Quantum Field Theory B; PHY 6937, Selected Topics in Physics (Materials Characterization); or PHY 6938, Selected Topics in Physics (Phase Transitions and Critical Phenomena). Though there are no other specific course requirements, the student is encouraged to take other specialized courses that are offered by the physics department. Please check the departmental Web page at http://physics.fsu.edu/grads/, as adjustments to the program of study are made routinely.

### Examinations

**Master’s Comprehensive Examination — PHY 8966.**** **For thesis students this examination is the defense of the thesis. For non-thesis students, this oral examination is given by three physics faculty members and covers the subjects of mechanics, quantum mechanics and electromagnetism. One of these areas, chosen by the student, will be examined at the graduate core course level. This examination is waived for students who have completed four of the graduate core courses with a grade of “B” or better.

**Qualifying Examination.** This examination is the written examination that all students must pass within the first two years to be able to continue toward the PhD degree. Any student who elects to strengthen their upper-level undergraduate physics background by taking one or more of our cross-listed undergraduate courses gets four tries at the written qualifier exam, but these start after their first year here, i.e. at the beginning of their second year.

**Preliminary Doctoral Exam — PHY 8964.**** **The PhD preliminary examination consists of: 1) a written tentative prospectus of a research topic suitable for PhD dissertation; and 2) an oral examination by the student’s supervisory committee on the tentative prospectus** **administered.

**PhD Dissertation Defense — PHY 8985.**** **The last examination is the oral dissertation defense given by the candidate’s Supervisory Committee, which has two parts: a public presentation of the dissertation topic, and second, a closed portion where only the graduate faculty can attend. The length of each portion is decided by the supervisory committee.

### Master’s Degree Requirements

Both thesis and non-thesis programs are offered leading to the master’s degree. The student must complete the specific course requirements listed above. Every candidate is required to teach one elementary laboratory for one semester.

To qualify for a non-thesis degree, a student must complete thirty-three semester hours in courses numbered 5000 and above. At least twenty-one semester hours must be taken on a letter grade basis.

Thesis students must complete thirty semester hours in courses numbered 5000 and above. At least eighteen semester hours must be taken on a letter grade basis. A minimum of six semester hours must be earned in PHY 5971 (Thesis).

For both thesis and non-thesis degrees, at least nine semester hours must be earned in the core courses PHY 5246, 5346, 5347, 5524, 5645 and 5646, including at least one course in quantum mechanics. In addition, no more than three semester hours each of PHY 5918 (Supervised Research) and 5940 (Supervised Teaching) may be counted toward the required semester hours.

### PhD Degree Requirements

A MS degree is not required for the PhD degree. Before a student can be admitted to candidacy for the PhD degree, the student must: 1) Pass all six graduate level courses with a cumulative grade average of no less than “B” and 2) pass the preliminary doctoral examination. In addition each doctoral candidate is required to teach two elementary laboratory sections for one semester. After completing all of the above mentioned requirements the student is admitted to PhD candidacy and can register for PHY 6980 (dissertation). There are time limits between examinations specified in the *Physics Graduate Studies Guide*. Students must have a minimum of twenty-four credit hours of PHY 6980: Dissertation before they can defend their Dissertation.

Each student is required to choose a major professor no later than during the second semester. The major professor, in consultation with the student, will form a supervisory committee no later than one month before the student is ready to take the oral portion of the preliminary doctoral examination. The committee must meet and review the student’s progress annually. The composition of the supervisory committee is specified in the *Physics Graduate Studies Guide*.

Research is an integral part of a PhD program and students are encouraged to start as soon as possible. No student can stay in the PhD program beyond the sixth semester (each summer counts as one semester) without giving evidence of explicit research accomplishments. The various options to satisfy this requirement are specified in the *Physics Graduate Studies Guide**.*
