Research Interests

Our group has broad research interests which span a range of problems in condensed matter physics. Much of the work centers on phase transitions and critical phenomena in magnets, alloys (including binary semiconductors), and equilibrium polymer systems. Emphasis is placed on high resolution simulations of static and dynamic properties of both bulk and surface properties using methods such as Monte Carlo, kinetic Monte Carlo, spin dynamics, and molecular dynamics. We also work on developing new methodologies and scalable algorithms for parallel supercomputers. We interact strongly with a number of other research groups in Europe and South America.
