Spin-orbit interaction and asymmetry effects on Kondo ridges at finite magnetic field
S. Grap, S. Andergassen, J. Paaske +1
We study electron transport through a serial double quantum dot with Rashba spin-orbit interaction (SOI) and Zeeman field of amplitude B in presence of local Coulomb repulsion. The…
Fermionic renormalization group methods for transport through inhomogeneous Luttinger liquids
V. Meden, S. Andergassen, T. Enss +2
We compare two fermionic renormalization group methods which have been used to investigate the electronic transport properties of one-dimensional metals with two-particle interacti…
A gentle introduction to the functional renormalization group: the Kondo effect in quantum dots
Sabine Andergassen, Tilman Enss, Christoph Karrasch +1
The functional renormalization group provides an efficient description of the interplay and competition of correlations on different energy scales in interacting Fermi systems. An…
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…
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…
