Theory of condensed matter, critical phenomena and computational physics.
My research covers a wide range of topics in theoretical condensed matter physics including spontaneous symmetry breaking and critical phenomena, renormalization group theory, and computational methods in quantum physics. In addition, I work closely with the experimental condensed matter group on ferroelectric materials and high-TC superconductivity. I am also part of a large international collaboration searching for axions coming from the core of the sun.
Most recently, my research has focused on microcanonical methods in statistical physics. I have developed the "microcanonical transfer matrix" which counts exactly the number of states with a given energy. With this new data we have been able to pursue the Yang-Lee theory of phase transitions for the Q-state Potts model. I have applied some of these same ideas to evaluating the Feynman path integral and am currently working on the quantum XY model.
