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…
Renormalization, Conservation Laws and Transport in Correlated Electron Systems
Tilman Enss
This thesis comprises two parts centered around the functional renormalization-group framework: in the first part, I study the role of symmetries and conservation laws in approxima…
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…
Ageing phenomena without detailed balance: the contact process
Tilman Enss, Malte Henkel, Alan Picone +1
The long-time dynamics of the 1D contact process suddenly brought out of an uncorrelated initial state is studied through a light-cone transfer-matrix renormalisation group approac…
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…
