Detailed Information

Programs of Study

The Department is committed to offering an outstanding graduate education in a broad range of fields in experimental and theoretical physics, including condensed-matter physics; elementary particle physics; biological physics; neuroscience; materials science; atomic, molecular, and optical physics; particle astrophysics; and gravitational physics. The Department has 45 faculty members and 120 graduate students. All of the faculty members are research active, and one third of the faculty was hired in the last six years. The Department is home to a major national center in materials science (MRSEC) and the Institute for Gravitation and the Cosmos (which includes Centers for Fundamental Theory, Gravitational Wave Physics, and Particle Astrophysics). The Department is thus very dynamic in research. There is a weekly colloquium series and several series of special lectures from distinguished physicists, in addition to approximately three to five specialized weekly physics seminars.

The graduate program is aimed primarily at the attainment of a Ph.D. degree in physics. An M.S. program is also offered. Upon arrival, each graduate student is appointed a mentoring committee to provide personalized guidance during graduate school. The first year of study covers basic courses in graduate physics. Arriving students with advanced backgrounds may obtain course exemptions, thus effectively becoming second-year students. During the second year, after passing the candidacy exam, students take advanced courses in their area of specialization, form a thesis committee, and choose a research adviser. Completion of all the Ph.D. requirements is typically accomplished in a total of five years. The M.S. degree is typically conferred after one year of research beyond the first-year graduate course work through the submission of a thesis, or at the end of two years of course work through a nonthesis (review paper) option.

Research Facilities

The Department occupies three adjoining buildings on campus. Extensive high-tech equipment is available for research, including state-of-the-art equipment for the study of ultracold atoms; thin-film preparation by sputtering and molecular-beam epitaxy; photoelectron spectrometers; numerous pulsed and continuous lasers; a variety of cryostats operating between 77K and 5mK; atomic-scale microscopes, including scanning tunneling microscopes (STM), field ion microscopes (FIM), and a field emission microscope (FEM); and a low-energy electron diffraction apparatus (LEED). Condensed-matter experimentalists make use of the excellent nanofabrication facilities on campus as well as the professionally staffed Departmental machine shop. Experimental high-energy physics research and condensed-matter experiments are also conducted at national facilities such as Brookhaven National Laboratory, CERN, and DESY (Hamburg, Germany). Physics faculty members are affiliated with international collaborations such as AMANDA, ICECUBE, and AUGER (experimental particle astrophysics) in Antarctica and South America, as well as LIGO and LISA (gravitational wave observatories). A combined Physical and Math Sciences Library is conveniently located in the same building as the physics department and also provides online access to journals. The Department has many networked UNIX, PC, and Macintosh workstations and various other computer facilities, including Beowulf Linux clusters, immersive virtual reality scientific visualization systems, and a high-speed network used for LIGO data analysis, as well as specially designed rooms for computer-based physics instruction. An SP2 parallel supercomputer is available at the University.

Financial Aid

The Department offers incoming students teaching assistantships with full coverage of tuition. The nine-month stipend for the assistantships was approximately $15,705 in 2008–09. Additional summer support of $2000 to $4000 is usually available. Graduate assistants average a total income of about $20,359 for twelve months from the assistantship stipend, summer wages, and possible Departmental awards. Students from their second year on are commonly supported by the research grants of their advisers through research assistantships. The Graduate School and the Eberly College of Science provide a few research fellowships and several supplemental fellowships for qualified students.

Cost of Study

Tuition costs for all incoming graduate students are covered by the Department. Tuition in 2008–09 was $7807 per semester (full-time), including a mandatory $222 information technology fee and a $74 activity fee. For 2008–09, tuition for a normal two-semester load was $15,614.

Living and Housing Costs

There is limited graduate student housing on campus (http://www.hfs.psu.edu/housing). Rentals in State College for a one-bedroom apartment range from $430 to $950 per month. Health-care coverage is offered at a rate of $401.20 per year to graduate assistants.

Student Group

The Department typically hosts about 120 graduate students with a variety of ethnic backgrounds and nationalities. The vast majority of students are on teaching or research assistantships. About 50 percent of the students are from the United States.

Location

The University Park campus of Penn State is home to 43,252 students, including 36,815 undergraduates and 6,437 graduate students, and 3,071 faculty members. It is located in the municipality of State College, nestled amid the picturesque valleys and wooded mountains of central Pennsylvania. State College has an airport with twelve departing and twelve arriving flights per day. The town is within 3½ hours’ driving distance of Pittsburgh; Washington, D.C.; and Philadelphia. New York City is 4½ hours away.

The University

Penn State, which was founded in 1855, is Pennsylvania’s land-grant university and has twenty-four campuses throughout the state. Penn State has more than 467,701 living alumni. One in every 127 Americans with college degrees and one in every 9 Pennsylvanians are graduates of Penn State. The University hosts a legendary football team, and its home turf, Beaver Stadium (capacity 107,282), is the second-largest university stadium in the United States.

Applying

The formal deadline for applications for the fall is April 15, but applications are reviewed beginning in late January until all assistantships are offered. GRE (especially Subject Test in physics) scores are strongly preferred. The TOEFL score is mandatory for students from non-English-speaking countries. Applications sent directly to the physics department do not initially require an application fee.
