Mean-field theory of Feshbach-resonant interactions in 85Rb condensates | Matt Mackie

28 Oct 2002 | Journal: | Phys Rev Lett, 89 (18), 180403 | Abstract: | Recent Feshbach-resonance experiments with 85Rb Bose-Einstein condensates have led to a host of unexplained results: dramatic losses of condensate atoms for an across-resonance sweep of the magnetic field, a collapsing condensate with a burst of atoms emanating from the remnant condensate, increased losses for decreasing interaction times, and coherent oscillations between remnant and burst atoms. Using a simple yet realistic mean-field model, we find that rogue dissociation, molecular dissociation to noncondensate atom pairs, is strongly implicated as the physical mechanism responsible for these observations. | Source: | PubMed, pmid12398586 | Services: | Forum | Review | Favorites |
