My research falls into three broad areas: (i) theoretical modeling of nanoscale electronics (tunnel junctions and thermoelectric coolers and power generators); (ii) quantum simulation with ultracold ions and ultracold atoms in optical lattices; and (iii) nonequilibrium effects and the violation of Ohm's law when electric fields become large. My work ranges from proving rigorous theorems on the many-body problem to calculating the superconducting transition temperature of a real material like sulfur under high pressure to modeling the nonlinear response of a Mott insulator to large electric fields. Most of my work also involves advanced numerical computation.
