Finite Temperature Density Matrix Renormalization using an enlarged Hilbert space

arXiv:cond-mat/0510124 · doi:10.1103/PhysRevB.72.220401

Abstract

We apply a generalization of the time-dependent DMRG to study finite temperature properties of several quantum spin chains, including the frustrated model. We discuss several practical issues with the method, including use of quantum numbers and finite size effects. We compare with transfer-matrix DMRG, finding that both methods produce excellent results.
