Condensed Matter Theory

The theorist’s toolbox has always included a pencil and paper, but over the past few decades computer programs have become increasingly important supplements to traditional methods of calculation. Our efforts have been primarily addressed to computationally intensive numerical studies of simple models relevant to physical systems in which disorder and/or quantum fluctuations play a central role. Such systems have included some of the most exciting recent developments in condensed matter physics: superconducting fullerides (compounds containing “buckyballs”), quantum antiferromagnets (most notably in the context of high temperature superconductivity), and the quantum Hall effect. The relevant models are often simple to formulate, but to solve them in any sense is a challenge.

My present interests are mostly in the areas of semiconductor nanostructures and magnetic flux patterns in “old-fashioned” (low temperature) superconductors.
