Quantum measures for density correlations in optical lattices
arXiv:0907.5129 · doi:10.1016/j.physleta.2009.07.078
Abstract
The density-density correlation profiles obtained superimposing absorption images from atomic clouds freely expanding after the release of the confining optical lattice can be theoretically described in terms of a generalized quantum measure based on coherent-like states. We show that the corresponding density patterns differ in a testable way from those computed using standard many-body mean values, usually adopted in fitting experimental data.
