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…
Cheers: a linear-scaling KBE+GKBA code
Y. Pavlyukh, R. Tuovinen, E. Perfetto +1
The interaction of electrons with quantized phonons and photons underlies the ultrafast dynamics of systems ranging from molecules to solids, giving rise to a plethora of physical…
Time-linear scaling NEGF methods for real-time simulations of interacting electrons and bosons. I. Formalism
Yaroslav Pavlyukh, Enrico Perfetto, Daniel Karlsson +2
Simulations of interacting electrons and bosons out of equilibrium, starting from first principles and aiming at realistic multiscale scenarios, is a grand theoretical challenge. H…
Mott metal-insulator transition from steady-state density functional theory
David Jacob, Gianluca Stefanucci, Stefan Kurth
We present a computationally efficient method to obtain the spectral function of bulk systems in the framework of steady-state density functional theory (i-DFT) using an idealized…
Fast Green's function method for ultrafast electron-boson dynamics
Daniel Karlsson, Robert van Leeuwen, Yaroslav Pavlyukh +2
The interaction of electrons with quantized phonons and photons underlies the ultrafast dynamics of systems ranging from molecules to solids, and it gives rise to a plethora of phy…
Dynamically screened vertex correction to
Y. Pavlyukh, G. Stefanucci, R. van Leeuwen
Diagrammatic perturbation theory is a powerful tool for the investigation of interacting many-body systems, the self-energy operator encoding all the variety of scattering proc…
