Competition between Vortex Unbinding and Tunneling in an Optical Lattice
arXiv:cond-mat/0701761 · doi:10.1103/PhysRevA.75.051603
Abstract
We study a system of two-dimensional Bose gases trapped in minima of a deep one-dimensional optical lattice potential. Increasing the tunneling amplitude between adjacent gases drives a deconfinement transition to a phase where coherence is established between neighboring two-dimensional gases. We compute the signature of this transition in the interference pattern of the system as well as in its rotational response, which provides a direct measurement of the superfluidity in the system.
