**Overview**

The Physics Department is a young department with exceptional strength in several areas. We invite applications from able students interested in experimental and theoretical surface physics and condensed matter physics; in experimental modern optics; in quantum gravity, quantum field theory, cosmology, and relativistic astrophysics; and in physics teaching at a high-school or college level. The primary goal of our graduate education is the training of creative research scientists.

Our research in gravitational physics is in several areas: In gravitational-wave astronomy, we play a leading role in the development for LIGO of templates to extract signals of gravitational-waves from the coalescence of binary neutron stars and from the stochastic background. In early cosmology, recent work includes renormalization methods to investigate inflationary models. In the quantum arena, work involves black-hole evaporation and information loss, and quantization of microscopic topological structures. In relativistic astrophysics we have established limits on the spin and mass of rotating neutron stars. Work in nuclear physics and particle physics includes a study incorporating gluon exchange and quark confining interactions into relativistic bound-state equations, and a study of production mechanisms for the Higgs boson and related intermediate mass bosons.

Research in theoretical physics also includes work in graph theory, fiber bundles, homotopy classes of diffeomorphisms, the quantum theory of measurement and black-hole entropy and information loss. Theoretical work in nonlinear dynamics and chaos concerns maps approximating dynamical systems.

Research in surface physics includes experimental work in electron microscopy, electron holography, electron diffraction, scanning tunneling microscopy and spectroscopy, atomic force microscopy, infrared spectroscopy, synchrotron radiation, and molecular beam epitaxy.

Theoretical work in surface physics focuses on the structure and dynamics of surfaces and interfaces. The theory groups have developed quantum mechanical multiple scattering theories for electron and positron diffraction, photoelectron diffraction, high-resolution electron-energy-loss spectroscopy, x-ray diffraction, and electron holography.

Experimental work in condensed matter physics is also being done in the areas of low-temperature physics, unconventional superconductivity (including high Tc), heavy fermions, materials synthesis and floating zone single crystal growth, oxides, magnetism, ultrasonics, and neutron diffraction. Theoretical work in condensed matter physics also includes research in quantum transport phenomena and electromigration in mesoscopic systems, and superconductivity.

Experimental work in modern optics is being done with ultrafast lasers to study the dynamics of physical, chemical, and biological systems on the molecular and cellular level.

Graduate Minor in Physics

A doctoral student in another department wishing to minor in Physics must choose a minor professor from among the Physics Graduate Faculty. The student and the minor professor plan a program of study consisting of 9 to 12 graduate credits in Physics and complete a Graduate Minor Program Plan for the Physics Department files.

## Master of Science in Physics

**Admission**

An applicant must meet Graduate School requirements plus these departmental requirements to be considered for admission to the program:

- Letters of Recommendation. Three letters of recommendation are required from persons familiar with the applicant’s academic work.
- Graduate Record Examinations. Both the General Test and the Subject Test in Physics are strongly encouraged (but not required).
- Undergraduate major in physics or related fields. Applicants may be admitted with specific program-defined course deficiencies provided that the deficiencies amount to no more than two courses.

**Major Professor as Advisor**

The student must have a major professor to advise and supervise the student’s studies as specified in Graduate School regulations. The newly admitted student is assigned to a temporary advisor.

Students in the master’s program who are planning to terminate their physics studies with a master’s degree should plan and prepare a program of study with the Department Master’s Program Advisor.

## Option 1: Thesis Option

**Credits and Courses**

Minimum degree requirement is 30 graduate credits, 18 of which must normally be in physics and 12 of which may be in related fields. Of the 18 credits earned in the Department, at least 6 must be in physics courses numbered above 700, with the remainder in courses at least above 500; research, seminar, and independent study credits do not satisfy the 700 requirement. Six credits are earned through the thesis.

**Thesis**

The student must write an acceptable thesis.

**Comprehensive Examination**

The student must pass a comprehensive oral examination, in part a defense of the thesis.

**Time Limit**

The student must complete all degree requirements within five years of initial enrollment.

## Option 2: Non-Thesis Option

**Credits and Courses**

Minimum degree requirement is 30 graduate credits, 18 of which must normally be in physics and 12 of which may be in related fields. Of the 18 credits earned in the Department, at least 6 must be in physics courses numbered above 700, with the remainder in courses at least above 500; research, seminar, and independent study credits do not satisfy the 700 requirement.

**Thesis**

Not required.

**Comprehensive Examination**

The student must pass a comprehensive written or oral examination. The non-thesis master’s Oral Examination should evaluate the student’s achievements in graduate courses and fulfillment of the goals of the student’s program of study. In particular, students should be familiar with the materials in the “core” courses (Physics 515, 531, 532, 711 and 720).

**Time Limit**

The student must complete all degree requirements within five years of initial enrollment.

## Doctor of Philosophy in Physics

**Admission**

Applicant must meet Graduate School requirements plus departmental requirements as given for admission to the master’s program. A master’s degree is not a prerequisite for this Ph.D. program.

**Reapplication**

A student who receives the master’s degree must formally reapply for admission to the Graduate School before continuing studies toward the Ph.D.

**Course of Study**

Minimum degree requirement is 54 graduate credits beyond the bachelor’s degree, at least 27 of which must be earned in residence at UWM. The student plans an individual program of studies in consultation with the major professor. Coursework must include a minimum of 12 credits in physics graduate courses in the 700-999 levels (not including 711, 720, 721, or 990). A student may elect to complete one of the following minor programs: a minor of 9 to 12 credits in a single department; a minor of 12 credits In two or more departments. Traditional fields for the minor are mathematics, other natural sciences, computer sciences and engineering. In planning a minor in a single department, the student is advised by the minor professor; in planning a minor in two or more departments, the student is advised by the major professor. The program of study is to be chosen with the major professor and the departmental academic graduate committee.

**Residence**

The student must meet minimum Graduate School residence requirements.

**Written Qualifying Examination**

Prior to taking the oral doctoral preliminary examination, the student must pass a written qualifying examination which evaluates the student’s general background in graduate-level physics. This examination is based on subject matter at least as advanced as the material covered by the non-thesis master’s comprehensive examination. A student may not continue in the physics graduate program after 4.5 years without having passed this examination.

**Doctoral Preliminary Examination and Doctoral Proposal Hearing**

The student must prepare a written proposal and pass an oral examination to qualify for formal admission to candidacy for the degree. The oral examination primarily seeks to determine the student’s preparation for independent research and the suitability of the proposed dissertation program. This examination shall be taken no later than four semesters after passing the written qualifying examination. However, no student will be required to take the oral examination earlier than the sixth semester of graduate work at UWM.

**Dissertation**

The candidate must present a dissertation reporting the results of an original and independent research investigation representing substantive creative contribution.

**Dissertation Defense**

The candidate must, as the final step toward the degree, pass an oral examination in defense of the dissertation.

**Time Limit**

All degree requirements must be completed within ten years from the date of initial enrollment in the doctoral program.
