Thermodynamic properties of Bose-Hubbard model.

ORAL

Abstract

We perform Monte Carlo simulations of bosons in a three-dimensional optical lattice. We present accurate data for the ground state phase diagram and for the finite-temperature thermodynamic properties, including specific heat and entropy. Our data form a basis for an accurate thermometry of the system.
