The role of contacts in transport through Luttinger liquid — •Katharina Janzen, Volker Meden, and Kurt Schönhammer — Friedrich Hund Platz 1 , 37077 Göttingen

We investigate how the linear conductance through a clean Luttinger liquid (quasi one-dimensional quantum wire of correlated electrons) is effected by the contacts. Two models are studied. In the first the inhomogeneous system is described by an effective hydrodynamic model (local Luttinger liquid) obtained from bosonization. Within this approach analytical results can be obtained that generalize earlier findings. In addition, we study a microscopic lattice model applying the functional renormalization group method. This allows a more detailed analysis of problem.
