Bose-Einstein condensates with attractive interactions on a ring | | G. M. Kavoulakis
; | | Date: |
29 Oct 2002 | | Journal: | Phys. Rev. A, 67 (2003) 011601(R) | | Subject: | cond-mat | | Affiliation: | LTH, Lund, Sweden | | Abstract: | Considering an effectively attractive quasi-one-dimensional Bose-Einstein condensate of atoms confined in a toroidal trap, we find that the system undergoes a phase transition from a uniform to a localized state, as the magnitude of the coupling constant increases. Both the mean-field approximation, as well as a diagonalization scheme are used to attack the problem. | | Source: | arXiv, cond-mat/0210640 | | Services: | Forum | Review | PDF | Favorites | |
