Nonequilibrium quantum transport through nanoscale junctions within the scattering-states numerical renormalization group approach — •Sebastian Schmitt and Frithjof B. Anders — Lehrstuhl für Theoretische Physik II, Technische Universität Dortmund, Otto-Hahn-Str. 4, 44221 Dortmund

We employ the recently developed scattering-states numerical renormalization group approach to open quantum systems to study nonequilibrium Green functions and current-voltage characteristics of nanoscale junctions for intermediate and large values of the Coulomb interaction U. In particular, the influence of charge fluctuations when approaching the strong-coupling regime is discussed.
