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…
An effective theory of Feshbach resonances and many-body properties of Fermi gases
G. M. Bruun, C. J. Pethick
For calculating low-energy properties of a dilute gas of atoms interacting via a Feshbach resonance, we develop an effective theory in which the parameters that enter are an atom-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…
