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 Ames Laboratory

We investigate electronic properties of strongly correlated quantum materials with a focus on non-equilibrium dynamics. We employ a combination of analytical and numerical techniques from field-theory and statistical mechanics, and also develop NISQ quantum computing algorithms for many-body models. Our research is often performed in collaboration with experimental colleagues.
