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…

Classical and Quantum Theory of Fluctuations for Many-Particle Systems out of Equilibrium

Erik Schroedter, Michael Bonitz

Correlated classical and quantum many-particle systems out of equilibrium are of high interest in many fields, including dense plasmas, correlated solids, and ultracold atoms. Accu…
