The goal of the Graduate Program in Physics is to develop individual creativity and expertise in the fields of physics. In pursuit of this objective, study in the program is strongly focused on research. Students are encouraged to begin participating in ongoing research activities from the beginning of their graduate studies. The research experience culminates with the doctoral dissertation, the essential element of the Ph.D. program that prepares the student for careers in academia, government laboratories, or industry.
A Master of Science degree is offered to those seeking to acquire or maintain technical mastery of both fundamentals and current applications.
A Master of Science degree in Applied Physics is offered for students wishing to emphasize applications encountered in most industrial and high technology environments.
Graduate Certificate programs are offered to those wishing to document graduate study in a broad discipline area. Such a program could be especially attractive to employees presently in the technology arena wishing to gain some exposure to recent advances. The certificate program may be incorporated into graduate degree programs in the Department of Physics, or may be taken on its own by nondegree seeking students, as well as students in other programs. Students in the certificate program are normally expected to have completed undergraduate courses in algebra and multi-variable calculus; students lacking appropriate preparation may be asked to take needed courses prior to admission to the program.
The University’s general admission requirements are discussed here.
The Physics Program seeks students who have a B.S. degree in Physics or closely related subjects from an accredited university or college, and who have superior skills in quantitative and deductive analysis. Decisions on admission are made on an individual basis. However, as a guide, a combined score on the verbal and quantitative parts of the GRE of 1100, or 700 on the quantitative part, is advisable based on our experience with student success in the program.
For graduate work it is assumed that the student has an undergraduate background that includes the following courses at the level indicated by texts referred to: mechanics at the level of Symon, Mechanics; electromagnetism at the level of Reitz and Milford, Foundations of Electromagnetic Theory; thermodynamics at the level of Kittel, Thermal Physics; and some upper-division course(s) in modern physics, quantum mechanics and atomic physics. Students who lack this foundation may be required to take one or more undergraduate courses to complete their preparation for graduate work.
The University’s general degree requirements are discussed here.
The candidate for either the M.S., MS in Applied Physics, or Ph.D. must satisfy general University degree requirements.
Well prepared students may demonstrate by examination adequate knowledge of the core and basic course material.
A limited number of assistantships are awarded to those students displaying the most promise in teaching or research. Specific decisions are made on an individual basis. Awardees are required to complete 8 graduate physics courses (not including research courses) during the first 12 months in residence. Continuation of support requires achievement of a minimum GPA of 3.3, and a satisfactory record in teaching or research assignments.
The central principle in the structure of the graduate program is that a student’s progress and ultimate success is best served by early and varied research experiences coupled with individually tailored course sequences.
Full-time students are urged to register for at least three hours of research every semester. Unless students already know unquestionably in which area they wish to specialize, they will be encouraged to participate in a different field of research each semester.
Current areas of research specialization in the Physics program are: Atmospheric and Space Physics; Atomic and Molecular Physics; Quantum Electronics and Applications; Optics; Relativity; Condensed Matter Physics; High Energy Physics and Elementary Particles; and Chemical Physics.
Research in Atmospheric and Space Physics encompasses both theory and experiment, with emphasis on aeronomy, ionospheric physics, planetary atmospheres, atmospheric electricity and its effects on weather and climate, and space instrumentation. Much of the research occurs in the W. B. Hanson Center for Space Sciences, which includes laboratory facilities for instrument design, fabrication, and testing. Faculty and students participate in ongoing satellite missions sponsored by NASA and DoD, and suborbital sounding rockets. They also participate in analysis of large data sets from previous missions, and from ground-based optical and radar instruments at locations ranging from Greenland to South America. Particular areas of interest include large and small scale dynamics and electrodynamics, numerical modeling of the thermosphere and ionosphere, characteristics of the near earth plasma environment, the effects of solar variability on atmospheric electricity, cloud microphysics and tropospheric dynamics, plasma instabilities and irregularities, and development and testing of innovative space flight instrumentation. Computer facilities include a network of dedicated workstations and access to supercomputers. For further details see http://www.utd500.utdallas.edu.
Experimental research in atomic and molecular physics is directed toward a more complete understanding of such processes as the dynamics of excitation and energy transfer, the thermal economy and transport properties that occur in a variety of plasma and discharge configurations.
Sophisticated diagnostic instrumentation used in these studies include ultraviolet, visible and infrared spectrometers and detectors, tunable pulsed and C. W. lasers, a shock tube facility and mass spectrometers. Several minicomputer systems are used for data acquisition and analysis.
Research in chemical physics centers on electrical and magnetic properties of conducting organic molecular crystals and polymers. A variety of laser-based diagnostic techniques for flame and combustion systems are under development. Examples include the detection of light atoms in flames, soot sizing and droplet/vapor evaporation processes. Intramolecular vibrational energy transfer and chemical reaction dynamics are studied via quantal and classical dynamics in computer simulations.
The group’s main activity is the BaBar experiment, at the PEP-II asymmetric b factory located at the Stanford Linear Accelerator Center (SLAC). BaBar has published the first statistically significant measurement of CP violation in the decays of bottom mesons and is exploring whether the origin of this CP violation lies within the Standard Model. BaBar data is fertile ground for precision and rare decays of bottom and charm particles, and tau lepton. BaBar’s goal is to explore CP violation in the decays of bottom mesons and to study bottom and charm meson decay. Research with BaBar is funded by the U.S. Department of Energy. The BaBar group specializes in high performance computing, simulation production, and data analysis while contributing to the operation of the experiment. Graduate students utilize the HEP group’s own Linux processing farm. With 128 CPU’s, it is the most powerful computing facility on campus, but is continually expanding to scale with the growing BaBar data set. UTD is networked to SLAC via Internet2.
Research in Optics in the UTD Physics Program concentrates in quantum optics, nonlinear optics and selected applications in physics and chemistry. Areas of particular interest include quantum coherence theory and the quantum statistical properties of light; the effects of coherent nonlinear-optical processes on the propagation of electromagnetic waves.
Quantum ElectronicsThe research effort in Quantum Electronics is devoted mainly to the development of new types of lasers from the visible to the gamma-ray spectrum and to multiphoton spectroscopy of atoms and molecules. High-resolution multiphoton spectroscopy and high-power charge-transfer lasers originated at the university. Major research equipment includes two intense electron-beam devices that are used to excite potential laser plasmas at power levels of 4 and 100 gigawatts, respectively, and a state-of-the-art Nd: YAG laser system. In experiments on atomic and molecular spectroscopy, both pulsed and continuous narrowband tunable dye lasers are being used for basic studies of atomic structure and molecular interatomic potentials.
This theoretical physics group studies fundamental problems in General Relativity and Relativistic Cosmology, such as the structure of the big bang, the role of inflation, the possible properties of dark matter and dark energy, and fitting model universes to the observational data. The group is also instrumental in organizing the biennial Texas Symposia on Relativistic Astrophysic, beginning in Dallas in 1963 and recurring regularly all over the world since then.
Materials Science is at the interface of many disciplines and involves a collaborative approach with colleagues in Chemistry, and Electrical Engineering. Our research facilities are distributed over the Physics Laboratories, NanoTech Institute and Electrical Engineering CleanRoom.Research in Materials Science involves both experiment and theory with emphasis on the physical aspects of Materials Science. A synopsis of our activities is given below: Measurements of optical properties of solids with emphasis on modulated reflectance and Raman scattering of semi-conductors are routinely carried out.
Various nanoscale and synthetic materials are being studied for their optical, electronic and transport properties, as well as applications in photonics and (opto)electronics. The materials of interest include nanostructures (quantum dots and wires, fullerenes and carbon nanotubes) and low-dimensional systems, photonic band gap crystals and “left-handed” electromagnetic meta-materials, organic and polymeric materials.
The interaction of nanoscale materials, such as carbon nanotubes, with biological entities are being investigated for prospective biomedical and electronic applications. For example, chemically functionalized carbon nanotubes are being studied as building blocks in transistor and sensor applications.
A minimum of 32 graduate credit hours are required. In order to receive the MSAP degree, students must successfully complete at least 16 semester credit hours of core courses. In addition to the core courses 16 additional credit hours may be chosen from the Physics elective courses listed below or from electrical engineering, computer science, biology, geosciences, chemistry and management courses. The complete list of these courses is in the Graduate Advisor’s office.
A minimum of 12 additional credit hours must be taken from the core list below. Elective courses totaling 16 additional credit hours may be chosen from the Physics elective courses listed below:
Up to 6 hours of an industrial internship or supervised research may be substituted for up to two of the elective courses. The following research courses will satisfy this requirement:
A minimum total of 32 graduate hours is required.
21 hours of physics courses to be selected by the student with the approval of the Graduate Adviser. Six hours of research including an M. S. thesis may be substituted for two of the elective courses.
A candidate for the Ph.D. must take the following 8 courses: PHYS 5311, 5313, 5322, 5401, 5402. 5421, 6300, and PHYS 6301. A candidate must also take a minimum of 4 elective courses, 2 from within his/her area of specialization and 2 selected from 2 different areas within the department. Additional courses may be required to satisfy the particular degree requirements and/or to ensure sufficient grounding in physical principles. The graduate advisor and/or the student’s supervisory committee must approve course selections. A minimum of one year residency after admission to the doctoral program is required.
When a student has completed the required course work with the minimum GPA of 3.3 and has decided upon his/her field of specialization, a committee is formed to guide the student’s dissertation work. Once a dissertation topic has been identified, the student must submit a proposal that outlines the present state of knowledge of the field and presents the research program the student expects to accomplish for the dissertation. This proposal must be approved by the committee and the Department Head.
A seminar on the dissertation proposal must be presented, followed by an oral examination conducted by the faculty on the proposed area of research and related topics. The Supervising Committee shall determine by means of the exam and any ancillary information whether the student is adequately prepared and has the ability to conduct independent research. This examination and the Committee’s evaluation constitute the Qualifying Examination. Failure of this examination is discussed under “Qualifying Examination” in General Academic Regulations in this catalog. The approved dissertation proposal is then filed with the Dean of Graduate Studies. The Qualifying Examination seminar must be held prior to the end of the third academic year (by May or December of the third year) in the Program for any type of financial support to be continued beyond that time.
A manuscript embodying a substantial portion of the dissertation research accomplished by the student must be submitted to a suitable professional refereed journal prior to the public seminar and dissertation defense. A public seminar, successful defense of the dissertation, and its acceptance by the Supervising Committee conclude the requirements for the Ph.D. In lieu of the traditional dissertation, and at the discretion of the supervising professor, a manuscript dissertation following the guidelines published by the Graduate Dean’s Office may be substituted.
