We present in detail a method we recently introduced [Phys. Rev. Lett. 103, 176404 (2009)
10.1103/PhysRevLett. 103.176404] to describe finite systems in and out of equilibrium …

We review one of the most versatile theoretical approaches to the study of time-dependent
correlated quantum transport in nano-systems: the non-equilibrium Green's function (NEGF) …

We study time-dependent electron transport through an Anderson model. The electronic
interactions on the impurity site are included via the self-energy approximations at Hartree …

We develop a new model to simulate nonradiative relaxation and dephasing by combining
real-time Hartree–Fock and density functional theory (DFT) with our recent open-systems …

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 …

The possibility of finding multistability in the density and current of an interacting nanoscale
junction coupled to semi-infinite leads is studied at various levels of approximation. The …

Electron transport in nanostructures is calculated and compared using a time-independent
and a time-dependent first-principles framework. The time-independent approach uses the …

In this book section, we give a brief introduction to many-body perturbation theory for
coupled fermion-boson systems using non-equilibrium Green's functions. Using the …

We present a method to perform stability analysis of nonequilibrium fixed points appearing
in self-consistent electron transport calculations. The nonequilibrium fixed points are given …

With this special issue of the European Physical Journal B we pay homage to the scientific
career of Eberhard Kurt Ulrich (Hardy) Gross (see Fig. 1), on occasion of his 65th birthday …
