Bogoliubov Theory of Dipolar Bose Gas in Weak Random Potential

الأصل · EN

We consider a dilute homogeneous Bose gas with both an isotropic short-range contact interaction and an anisotropic long-range dipole-dipole interaction in a weak random potential at low temperature in three dimensions. Within the realm of Bogoliubov theory we analyze how both condensate and superfluid depletion are depleted due to quantum and thermal fluctuations as well as disorder fluctuations.
