Anisotropic Superfluidity in a Dipolar Bose Gas
Anisotropic Superfluidity in a Dipolar Bose Gas
We study the superfluid character of a dipolar Bose-Einstein condensate (DBEC) in a quasi-two dimensional geometry. We consider the dipole polarization to have some nonzero projection into the plane of the condensate so that the effective interaction is anisotropic in this plane, yielding an anisotropic dispersion relation. By performing direct …
