Semiclassical theory of electron drag in strong magnetic fields

Sergej Brener, Walter Metzner

We present a semiclassical theory for electron drag between two parallel two-dimensional electron systems in a strong magnetic field, which provides a transparent picture of the mo…

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…

Renormalization group flows into phases with broken symmetry

Manfred Salmhofer, Carsten Honerkamp, Walter Metzner +1

We describe a way to continue the fermionic renormalization group flow into phases with broken global symmetry. The method does not require a Hubbard-Stratonovich decoupling of the…

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…
