Interplay of the Aharonov-Bohm effect and Klein tunneling in graphene
Jörg Schelter, Dan Bohr, Björn Trauzettel
We numerically investigate the effect of Klein tunneling on the Aharonov-Bohm oscillations in graphene rings using a tight-binding model with nearest-neighbor couplings. In order t…
Interplay between interference and Coulomb interaction in the ferromagnetic Anderson model with applied magnetic field
Jonas Nyvold Pedersen, Dan Bohr, Andreas Wacker +3
We study the competition between interference due to multiple single-particle paths and Coulomb interaction in a simple model of an Anderson-like impurity with local-magnetic-field…
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…
