Kondo physics in transport through a quantum dot with Luttinger liquid leads
S. Andergassen, T. Enss, V. Meden
We study the gate voltage dependence of the linear conductance through a quantum dot coupled to one-dimensional leads. For interacting dot electrons but noninteracting leads Kondo…
Renormalization-group analysis of the one-dimensional extended Hubbard model with a single impurity
S. Andergassen, T. Enss, V. Meden +3
We analyze the one-dimensional extended Hubbard model with a single static impurity by using a computational technique based on the functional renormalization group. This extends p…
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…
Interaction flow method for many-fermion systems
Carsten Honerkamp, Daniel Rohe, Sabine Andergassen +1
We propose an interaction flow scheme that sums up the perturbation expansion of many-particle systems by successively increasing the interaction strength. It combines the unbiased…
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…
