Auxiliary master equation approach within stochastic wave functions: Application to the Interacting Resonant Level Model
Max E. Sorantin, Delia M. Fugger, Antonius Dorda +2
We present further developments of the auxiliary master equation approach (AMEA), a numerical method to simulate many-body quantum systems in as well as out of equilibrium, and app…
Charge redistribution in correlated heterostuctures within nonequilibrium real-space dynamical mean-field theory
Irakli Titvinidze, Max E. Sorantin, Antonius Dorda +2
We address the steady-state behavior of a system consisting of several correlated monoatomic layers sandwiched between two metallic leads under the influence of a bias voltage. In…
