Bose-Einstein-condensed gases with arbitrary strong interactions
arXiv:cond-mat/0701407 · doi:10.1103/PhysRevA.74.063623
Abstract
Bose-condensed gases are considered with an effective interaction strength varying in the whole range of the values between zero and infinity. The consideration is based on the usage of a representative statistical ensemble for Bose systems with broken global gauge symmetry. Practical calculations are illustrated for a uniform Bose gas at zero temperature, employing a self-consistent mean-field theory, which is both conserving and gapless.
