29 Mar 1999 | | Journal: | Phys. Rev. A, 60 (1999) R765 | | Subject: | cond-mat | | Affiliation: | School of Chemistry, Tel Aviv University, Tel Aviv, Israel Atomic Physics Division, NIST, Gaithersburg, USA | | Abstract: | In recent experiments on Na Bose-Einstein condensates [S. Inouye et al, Nature 392, 151 (1998); J. Stenger et al, Phys. Rev. Lett. 82, 2422 (1999)], large loss rates were observed when a time-varying magnetic field was used to tune a molecular Feshbach resonance state near the state of pairs of atoms belonging to the condensate many-body wavefunction. A mechanism is offered here to account for the observed losses, based on the deactivation of the resonant molecular state by interaction with a third condensate atom. | | Source: | arXiv, cond-mat/9903414 | | Services: | Forum | Review | PDF | Favorites | |
