A microscopic model for a class of mixed-spin quantum antiferromagnets
J. V. Alvarez, Roser Valenti, A. Zheludev
We propose a microscopic model that describes the magnetic behavior of the mixed-spin quantum systems RBaNiO (R= magnetic rare earth). An evaluation of the properties of th…
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…
