Landau levels and the Thomas-Fermi structure of rapidly rotating Bose-Einstein condensates
Gentaro Watanabe, Gordon Baym, C. J. Pethick
We show that, within mean-field theory, the density profile of a rapidly rotating harmonically trapped Bose-Einstein condensate is of the Thomas-Fermi form as long as the number of…
Global structure of Bose-Einstein condensates at high rotation: Beyond the lowest Landau level description
Gentaro Watanabe, C. J. Pethick
We study the global density profile of a rapidly rotating Bose-Einstein condensate in a harmonic trap with transverse frequency . By introducing an additional variationa…
Vortex core structure and global properties of rapidly rotating Bose-Einstein condensates
Gordon Baym, C. J. Pethick
We develop an approach for calculating stationary states of rotating Bose-Einstein condensates in harmonic traps which is applicable for arbitrary ratios of the rotation frequency…
Spatial period-doubling in Bose-Einstein condensates in an optical lattice
M. Machholm, A. Nicolin, C. J. Pethick +1
We demonstrate that there exist stationary states of Bose-Einstein condensates in an optical lattice that do not satisfy the usual Bloch periodicity condition. Using the discrete m…
Band structure, elementary excitations, and stability of a Bose-Einstein condensate in a periodic potential
M. Machholm, C. J. Pethick, H. Smith
We investigate the band structure of a Bose-Einstein condensate in a one-dimensional periodic potential by calculating stationary solutions of the Gross-Pitaevskii equation which h…
