Time-linear scaling NEGF methods for real-time simulations of interacting electrons and bosons. II. Dynamics of polarons and doublons
Yaroslav Pavlyukh, Enrico Perfetto, Daniel Karlsson +2
Nonequilibrium dynamics of the open chain Holstein-Hubbard model is studied using the linear time-scaling GKBA+ODE scheme developed in the preceeding paper. We focus on the set of…
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…
Real-time GW: Toward an ab initio description of the ultrafast carrier and exciton dynamics in two-dimensional materials
E. Perfetto, Y. Pavlyukh, G. Stefanucci
We demonstrate the feasibility of the time-linear scaling formulation of the method [Phys. Rev. Lett. {\bf 124}, 076601 (2020)] for {\it ab initio} simulations of optically dr…
Coherence and de-coherence in the Time-Resolved ARPES of realistic materials: an ab-initio perspective
Andrea Marini, Enrico Perfetto, Gianluca Stefanucci
Coherence and de-coherence are the most fundamental steps that follow the initial photo-excitation occurring in typical Pump&Probe experiments. Indeed, the initial external laser p…
Thermoelectric transport within density functional theory
Nahual Sobrino, Florian Eich, Gianluca Stefanucci +2
A new formalism to describe steady-state electronic and thermal transport in the framework of density functional theory is presented. A one-to-one correspondence is proven between…
From carriers and virtual excitons to exciton populations: Insights into time-resolved ARPES spectra from an exactly solvable model
G. Stefanucci, E. Perfetto
We calculate the {\em exact} time-resolved ARPES spectrum of a two-band model semiconductor driven out of equilibrium by resonant and nonresonant laser pulses, highlighting the eff…
