Finite-temperature properties of one-dimensional hard-core bosons in a quasiperiodic optical lattice (1111.2201v2)
Published 9 Nov 2011 in cond-mat.quant-gas and cond-mat.stat-mech
Abstract: We investigate the properties of impenetrable bosons confined in a one-dimensional lattice at finite temperature in the presence of an additional incommensurate periodic potential. Relying on the exact Fermi-Bose mapping, we study the effects of temperature on the one-particle density matrix and related quantities such as the momentum distribution function and the natural orbitals. We found evidence of a finite-temperature crossover related to the zero-temperature superfluid-to-Bose-glass transition that induces a delocalization of the lowest natural orbitals.
