Abstract
Formation of Atomic Pairs by dissociation of a molecular condensate or by inelastic collisions in an atomic condensate due to time-dependent curve crossing is studied beyond the mean-field approximation. The number of atoms formed by the spontaneous process is described by a Landau-Zener formula multiplied by an exponential amplification factor due to quantum many-body effects. The atomic pairs are formed in an entangled (squeezed) state. The rate of stimulated processes depends on the relative phase of the two fields.
