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. In addition, his research includes studies of vortex matter in superconducting systems, in which the competition between interactions of the vortices among themselves and with defects in the materials leads to pinning phenomena, of fundamental as well as practical interest. Professor Fertig has also been studying the statistical mechanics of topological defects (vortices and domain walls) in two-dimensional systems to understand their impact on the phases of several condensed matter systems.
