Real-time Dyson expansion for the nonequilibrium approximation: Correlated spectra and dependence on the reference propagator
Erik Schroedter, Jan-Philip Joost, Michael Bonitz +1
Electronic spectra provide direct insight into the excitations and correlations of condensed matter systems. Their description requires electron correlations beyond mean field. In…

Nonequilibrium Green Functions Simulations for Large Correlated Systems
Erik Schroedter, Michael Bonitz, Jan-Philip Joost
Correlated real-time dynamics in large, spatially inhomogeneous quantum systems remain difficult to access with nonequilibrium many-body methods. Two-time nonequilibrium Green func…
