Phases in an anisotropic two-dimensional optical lattice

ORAL

Abstract

We have studied the effects of anisotropy on a two-dimensional optical lattice using quantum Monte Carlo simulations. For finite lengths, such a system undergoes a one-dimensional quantum phase transition to a 1D Mott insulator of decoupled chains. Time of flight pictures and other measurable observables are calculated for a specified experimental setup.
