condensed matter physics (theoretical)

Professor Fertig is interested in the theoretical physics of low dimensional condensed matter systems. These include the two-dimensional electron gas, which supports an amazingly broad variety of phenomena and states: the quantum Hall effect, metal-insulator transitions, electron crystals, highly correlated metals, striped states, and quantum ferromagnetism. Recently he has been studying the electronic properties of topological electron systems, as well as graphene, a new two-dimensional material in which the electrons behave as massless relativistic particles, leading to bizarre, fascinating, and possible useful properties.
