Current research is primarily high-temperature superconductivity theory. Recent work includes model studies of doped Mott insulators, computation spectroscopic quantities -- optical conductivity, magnetic susceptibility, photoemission -- from first principles, and development of new mathematical methods based on the fractional quantum Hall effect. These include the use of condensed matter lattice gauge theories, the use of quasiparticles carrying fractional quantum numbers, and the application of conventional Feynman rules to systems containing both. Other interests include the theory of metals, localization, and quantum chaos. physics beyond the Standard Model, and vacuum structure of field theories.
