Description

I will highlight recent advances in the study of correlated Mott systems driven into nonequilibrium steady states. The analysis is based on an impurity solver that combines Keldysh Green’s functions with the Lindblad formalism for open quantum systems [1], embedded within nonequilibrium Dynamical Mean-Field Theory. Recent methodological improvements including a Configuration Interaction treatment of the many body Lindblad equation combined with a linear functional interpolation [2] allow to address scaling behavior in the Kondo regime.
I will present results for nonequilibrium phenomena such as photovoltaic effects impact ionization in photoexcited Mott insulators and present a recent mixed configuration scheme to address correlated multiorbital systems and realistic material simulations out of equilibrium [3].
