Our Theoretical Condensed Matter Research Group is based at the Department of Physics and Astronomy at Iowa State University, and embedded in the lively condensed matter research environment of Iowa State University and the Ames Laboratory. We investigate non-equilibrium dynamics of strongly correlated quantum materials and the effects of competing interactions and emergent order on the electronic properties of solids. To approach these questions we employ a combination of analytical and numerical techniques from field-theory and statistical mechanics. Our research is often guided by experimental results and strives to understand the impact of strong interactions on the properties of quantum materials.
