We present a brief pedagogical review of theoretical Green's function methods applicable to
open quantum systems out of equilibrium, in general, and single molecule junctions, in …

We give a detailed comparison of the hierarchical quantum master equation (HQME)
method to a continuous-time quantum Monte Carlo (CT-QMC) approach, assessing the …

We employ the recently proposed scattering states numerical renormalization group (SNRG)
approach to calculate I (V) and the differential conductance through a single molecular level …

We show that an open fermionic system coupled to a continuous environment with unitary
system-environment evolution can be exactly mapped onto an auxiliary system consisting of …

We present a Kadanoff-Baym formalism to study time-dependent phenomena for systems of
interacting electrons and phonons in the framework of many-body perturbation theory. The …

We address the fundamental question how the spatial Kondo correlations are building up in
time assuming an initially decoupled impurity spin S ⃗ imp. We investigate the time …

A fast time propagation method for nonequilibrium Green's functions (NEGF) based on the
generalized Kadanoff–Baym Ansatz (GKBA) is applied to a lattice system with a symmetry …
