Kadanoff-Baym equations and approximate double occupancy in a Hubbard dimer
M. Puig von Friesen, C. Verdozzi, C. -O. Almbladh
We use the Kadanoff-Baym equations within the framework of many-body perturbation theory to study the double occupancies in a Hubbard dimer. The double occupancies are obtained fro…

Kadanoff-Baym description of Hubbard clusters out of equilibrium: performance of many-body schemes, correlation-induced damping and multiple steady states
M. Puig von Friesen, C. Verdozzi, C. -O. Almbladh
We present in detail a method we recently introduced (PRL. 103, 176404 (2009)) to describe finite systems in and out of equilibrium, where the evolution in time is performed via th…
