Dislocation-Mediated Melting in Superfluid Vortex Lattices
S. Andrew Gifford, Gordon Baym
We describe thermal melting of the two-dimensional vortex lattice in a rotating superfluid by generalizing the Halperin and Nelson theory of dislocation-mediated melting. and deriv…
Non-uniform vortex lattices in inhomogeneous rotating Bose-Einstein condensates
Gordon Baym, C. J. Pethick, S. Andrew Gifford +1
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 an…
Structure of vortices in rotating Bose-Einstein condensates
Gentaro Watanabe, S. Andrew Gifford, Gordon Baym +1
We calculate the structure of individual vortices in rotating Bose-Einstein condensates in a transverse harmonic trap. Making a Wigner-Seitz approximation for the unit cell of the…
Vortex lattice stability and phase coherence in three-dimensional rapidly rotating Bose condensates
S. Andrew Gifford, Gordon Baym
We establish the general equations of motion for the modes of a vortex lattice in a rapidly rotating Bose-Einstein condensate in three dimensions, taking into account the elastic e…
