Low-temperature transport in Heisenberg chains

J. V. Alvarez, Claudius Gros

A technique to determine accurately transport properties of integrable and non-integrable quantum-spin chains at finite temperatures by Quantum Monte-Carlo is presented. The reduct…

Fermi surface renormalization in Hubbard ladders

Kim Louis, J. V. Alvarez, Claudius Gros

We derive the one-loop renormalization equations for the shift in the Fermi-wavevectors for one-dimensional interacting models with four Fermi-points (two left and two right movers…

Modeling the electronic behavior of -LiV2O5: a microscopic study

R. Valenti, T. Saha-Dasgupta, J. V. Alvarez +2

We determine the electronic structure of the one-dimensional spin-1/2 Heisenberg compound -LiVO, which has two inequivalent vanadium ions, V(1) and V(2), via density-fun…

Can a frustrated spin-cluster model describe the low-temperature physics of NaV_2O_5 ?

Claudius Gros, Roser Valenti, J. V. Alvarez +2

Recent experimental evidence suggest the existence of three distinct V-valence states (V^{+4}, V^{+4.5} and V^{+5}) in the low-temperature phase of NaV_2O_5 in apparent discrepancy…

On the evaluation of the specific heat and general off-diagonal n-point correlation functions within the loop algorithm

J. V. Alvarez, Claudius Gros

We present an efficient way to compute diagonal and off-diagonal n-point correlation functions for quantum spin-systems within the loop algorithm. We show that the general rules fo…
