Developments in many-body theory of quantum transport and spectroscopy with non-equilibrium Green's functions and time-dependent density functional theory
Uimonen, Anna-Maija (University of Jyväskylä, 2015)The problem of quantum dynamics in open systems has gained attention in recent decades and not the least due to the advances made in quantum transport in molecular systems. The main motivation behind quantum transport ... -
Merging Features from Green's Functions and Time Dependent Density Functional Theory : A Route to the Description of Correlated Materials out of Equilibrium?
Hopjan, M.; Karlsson, Daniel; Ydman, S.; Verdozzi, C.; Almbladh, C.-O. (American Physical Society, 2016)We propose a description of nonequilibrium systems via a simple protocol that combines exchangecorrelation potentials from density functional theory with self-energies of many-body perturbation theory. The approach, aimed ... -
Time-dependent quantum transport in nanosystems : a nonequilibrium Green's function approach
Tuovinen, Riku (University of Jyväskylä, 2016)A time-dependent extension to the Landauer–Büttiker approach to study transient quantum transport in arbitrary junctions composed of leads and conducting devices is developed. The nonequilibrium Green’s function approach ... -

Time-dependent density-functional theory for strongly interacting electrons
Cort Barrada, Luis; Karlsson, Daniel; Lani, Giovanna; van Leeuwen, Robert (American Physical Society, 2017)We consider an analytically solvable model of two interacting electrons that allows for the calculation of the exact exchange-correlation kernel of time-dependent density functional theory. This kernel, as well as ...
