Spectral and transport properties of one-dimensional correlated electrons — •Volker Meden — Institut für Theorie der Statistischen Physik, RWTH Aachen University
Two-particle interactions strongly alter the low-energy physics of electrons confined to one spatial dimension. Excitations cannot be described by fermionic quasi-particles. Metallic systems of this type fall into the Luttinger liquid universality class and are characterized by power-law decay of correlation functions. I will give an overview over the one-particle spectral and transport properties of such systems including a discussion of the model dependent low-energy scale beyond which Luttinger liquid power laws are observable. Leaving the framework of equilibrium physics I will report on recent progress in understanding the non-equilibrium steady state as well as relaxation dynamics of isolated and contacted quantum wires.
