## Condensed Matter Physics

There are numerous graduate students and postdocs working in condensed matter physics and statistical mechanics.

Several people working in this area are also members of the Center for Simulational Physics.

The department offers several advanced graduate courses in condensed matter theory, many-body theory, mathematical and computational methods, and statistical mechanics.
