Research

Stuart’s research is in theoretical condensed matter physics.  Recent focus areas include ultrafast optical probes of correlated systems, the quantum dynamics of coupled systems, quasiparticle formation, and inelastic tunneling between and into nanowires.  He is also interested in the physics of polarons, colossal magnetoresistance materials, high temperature superconductors, heavy fermions, multiferroics, the quantum Hall effect, and linear and nonlinear transport in novel and disordered materials.
