摘要: A homogeneous polarized dipolar Bose-Einstein condensate is considered in the presence of weak quenched disorder within mean-field theory at zero temperature. By first solving perturbatively underlying Gross-Pitaevskii equation and then performing ensemble averages for physical observables, it shown that anisotropy two-particle interaction passed on to both superfluid density sound velocity.
