Long-range correlations of density in a Bose-Einstein condensate expanding in a random potential
arXiv:0807.2954 · doi:10.1103/PhysRevLett.101.190406
Abstract
We study correlations of atomic density in a weakly interacting Bose-Einstein condensate, expanding diffusively in a random potential. We show that these correlations are long-range and that they are strongly enhanced at long times. Density at distant points exhibits negative correlations.
