Conductivity of quantum-spin chains: A Quantum Monte Carlo approach
J. V. Alvarez, Claudius Gros
We discuss zero-frequency transport properties of various spin-1/2 chains. We show, that a careful analysis of Quantum Monte-Carlo (QMC) data on the imaginary axis allows to distin…

Properties of electrons near a Van Hove singularity
M. A. H. Vozmediano, J. Gonzalez, F. Guinea +2
The Fermi surface of most hole-doped cuprates is close to a Van Hove singularity at the M point. A two-dimensional electronic system, whose Fermi surface is close to a Van Hove sin…

Anomalous thermal conductivity of frustrated Heisenberg spin-chains and ladders
J. V. Alvarez, Claudius Gros
We study the thermal transport properties of several quantum spin chains and ladders. We find indications for a diverging thermal conductivity at finite temperatures for the models…
