Can we always get the entanglement entropy from the Kadanoff-Baym equations? The case of the T-matrix approximation
M. Puig von Friesen, C. Verdozzi, C. -O. Almbladh
We study the time-dependent transmission of entanglement entropy through an out-of-equilibrium model interacting device in a quantum transport set-up. The dynamics is performed via…
Some open questions in TDDFT: Clues from Lattice Models and Kadanoff-Baym Dynamics
Claudio Verdozzi, Daniel Karlsson, Marc Puig von Friesen +2
Two aspects of TDDFT, the linear response approach and the adiabatic local density approximation, are examined from the perspective of lattice models. To this end, we review the DF…
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…
Successes and Failures of Kadanoff-Baym Dynamics in Hubbard Nanoclusters
Marc Puig von Friesen, Claudio Verdozzi, Carl-Olof Almbladh
We study the non-equilibrium dynamics of small, strongly correlated clusters, described by a Hubbard Hamiltonian, by propagating in time the Kadanoff-Baym equations within the Hart…
