Resumen:
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.
