Static properties of positive ions in atomic Bose-Einstein condensates
P. Massignan, C. J. Pethick, H. Smith
The excess number of atoms around an ion immersed in a Bose-Einstein condensate is determined as a function of the condensate density far from the ion. We use thermodynamic argumen…
Static response of Fermi liquids with tensor interactions
E. Olsson, P. Haensel, C. J. Pethick
We use Landau's theory of a normal Fermi liquid to derive expressions for the static response of a system with a general tensor interaction that conserves the total spin and the to…
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…
