Nonuniform vortex lattices in inhomogeneous rotating Bose-Einstein condensates
Nonuniform vortex lattices in inhomogeneous rotating Bose-Einstein condensates
We derive a general framework, in terms of elastic theory, for describing the distortion of the vortex lattice in a rotating Bose-Einstein condensate at arbitrary rotation speed and determining the dependence of the distortion on the density inhomogeneity of the system. In the rapidly rotating limit, we derive the energetics …
