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…
Photoinduced dynamics of organic molecules using nonequilibrium Green's functions with second-Born, , -matrix and three-particle ladder correlations
Yaroslav Pavlyukh, Enrico Perfetto, Gianluca Stefanucci
The ultrafast hole dynamics triggered by the photoexcitation of molecular targets is a highly correlated process even for those systems, like organic molecules, having a weakly cor…
