Abstract

Loss of atoms from a 85 Rb condensate on passage through a Feshbach resonance is analysed using the generalized parametric approximation that takes into account quantum many-body effects. These effects lead to a substantial increase of the losses. A better agreement with experiments is achieved, compared to predictions of mean-field theories. The method provides much insight into the quantum effects involved, and into the nature of entangled atom pairs produced by the loss.
