Squeezed Condensates
  We analyse the atomic state obtained by photo-dissociation of a molecular Bose-Einstein-condensate. This process is equivalent to down-conversion in quantum optics where it is responsible for squeezing of the field amplitudes. Monte Carlo simulations derived from the Positive P description of the system, and approximate equations for second moments of the atomic field operators are introduced to describe the early stages of the process -- not amenable to the usual mean-field description.
