Strong enhancement of transport by interaction on contact links
Dan Bohr, Peter Schmitteckert
Strong repulsive interactions within a one dimensional Fermi system in a two-probe configuration normally lead to a reduced off-resonance conductance. We show that if the repulsive…

DMRG evaluation of the Kubo formula -- Conductance of strongly interacting quantum systems
Dan Bohr, Peter Schmitteckert, Peter Woelfle
In this paper we present a novel approach combining linear response theory (Kubo) for the conductance and the Density Matrix Renormalization Group (DMRG). The system considered is…
