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…

Cost Reduction in Spin-dependent Stochastic GW Calculations
Xuance Jiang, Vojtech Vlcek
We extend the stochastic GW (sGW) formalism to fully spin-polarized systems, encompassing both collinear and non-collinear spin configurations. For non-collinear systems-where Kohn…
