Correlated directional atomic clouds via four-heterowave mixing
arXiv:1003.3365 · doi:10.1103/PhysRevA.81.031606
Abstract
We investigate the coherence properties of pairs of counter-propagating atomic clouds, produced in superradiant Rayleigh scattering off atomic condensates. It is shown that these clouds exhibit long-range spatial coherence and strong nonclassical density cross-correlations, which make this scheme a promising candidate for the production of highly directional nonclassically correlated atomic pulses.
