H-NESSi: The Hierarchical Non-Equilibrium Systems Simulation package
Thomas Blommel, Jeremija Kovačević, Jason Kaye +3
We present H-NESSi (The Hierarchical Non-Equilibrium Systems Simulation package), an open-source software package for solving the Kadanoff-Baym equations (KBE) of nonequilibrium Gr…
Influence of Markovianity and self-consistency on time-resolved spectral functions of driven quantum systems
Thomas Blommel, M. Rey Lambert, Michael A. Kurniawan +2
We present a systematic comparison of the real-time Dyson expansion (RTDE) with established non-equilibrium Green's function approaches for simulating driven, interacting quantum s…
Many-Body Perturbation Theory for Driven Dissipative Quasiparticle Flows and Fluctuations
Thomas Blommel, Enrico Perfetto, Gianluca Stefanucci +1
We present a unified many-body perturbation theory for open quantum systems, that treats dissipation, correlations, and external driving on equal footing. Using a Keldysh-Lindblad…
A Unified Simulation Framework for Correlated Driven-Dissipative Quantum Dynamics
Thomas Blommel, Enrico Perfetto, Gianluca Stefanucci +1
Time-resolved photoemission spectroscopy provides a unique and direct way to explore the real-time nonequilibrium dynamics of electrons and holes. The formal theory of the spectral…
