Dipolar Bose-Einstein Condensates in Weak Anisotropic Disorder

  title={Dipolar Bose-Einstein Condensates in Weak Anisotropic Disorder},

  journal={Physical Review A},
Here we study properties of a homogeneous dipolar Bose-Einstein condensate in a weak anisotropic random potential with Lorentzian correlation at zero temperature. To this end we solve perturbatively the Gross-Pitaevskii equation to second order in the random potential strength and obtain analytic results for the disorder ensemble averages of both the condensate and the superfluid depletion, the equation of state, and the sound velocity. For a pure contact interaction and a vanishing correlation… Expand
