Short Summary

We plan to investigate a wide range of electronic correlation phenomena in models and materials under equilibrium and nonequilibrium conditions, using theoretical tools that include both analytic approaches as well as extensive numerical computations of electronic and structural materials properties. This includes the analysis of Compton profiles in transition metals, abinitio studies of Anderson localization in the presence of interactions, and calculation of non-equilibrium properties of periodically driven correlated systems.
