Impurity and correlation effects on transport in one-dimensional quantum wires
T. Enss, V. Meden, S. Andergassen +3
We study transport through a one-dimensional quantum wire of correlated fermions connected to semi-infinite leads. The wire contains either a single impurity or two barriers, the l…
Pseudogap at hot spots in the two-dimensional Hubbard model at weak coupling
Daniel Rohe, Walter Metzner
We analyze the interaction-induced renormalization of single-particle excitations in the two-dimensional Hubbard model at weak coupling using the Wick-ordered version of the functi…
Correlation effects on resonant tunneling in one-dimensional quantum wires
V. Meden, T. Enss, S. Andergassen +2
We study resonant tunneling in a Luttinger liquid with a double barrier enclosing a dot region. Within a microscopic model calculation the conductance G as a function of temperatur…
Functional renormalization group for Luttinger liquids with impurities
S. Andergassen, T. Enss, V. Meden +3
We improve the recently developed functional renormalization group (fRG) for impurities and boundaries in Luttinger liquids by including renormalization of the two-particle interac…
