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…
Condensate superfluidity and infrared structure: the Josephson relation
Markus Holzmann, Gordon Baym
We derive the Josephson relation in a superfluid between the condensate density, the superfluid mass density, and the infrared structure of the single particle Green's function by…
Tkachenko modes of vortex lattices in rapidly rotating Bose-Einstein condensates
Gordon Baym
We calculate the in-plane modes of the vortex lattice in a rotating Bose condensate from the Thomas-Fermi to the mean-field quantum Hall regimes. The Tkachenko mode frequency goes…
Rapidly rotating Bose-Einstein condensates in anharmonic potentials
George Kavoulakis, Gordon Baym
Rapidly rotating Bose-Einstein condensates confined in anharmonic traps can exhibit a rich variety of vortex phases, including a vortex lattice, a vortex lattice with a hole, and a…
Finite Temperature Collapse of a Bose Gas with Attractive Interactions (extended version)
Erich J. Mueller, Gordon Baym
We study the mechanical stability of the weakly interacting Bose gas with attractive interactions, and construct a unified picture of the collapse valid from the low temperature co…
