Dynamical mean-field study of strongly interacting Bose-Einstein condensate

Abstract The experimental results of 85 Rb Bose–Einstein condensates are analyzed within the mean-field approximation with time-dependent two-body interaction and dissipation due to three-body recombination. We found that the magnitude of the dissipation is consistent with the three-body theory for longer rise times. However, for shorter rise times, it occurs an enhancement of this parameter, consistent with a coherent dimer formation.
