First-principles quantum simulations of dissociation of molecular condensates:Atom correlations in momentum space

Savage, Craig; Schewenn, P.E; Kheruntsyan, Karen V


We investigate the quantum many-body dynamics of dissociation of a Bose-Einstein condensate of molecular dimers into pairs of constituent bosonic atoms and analyze the resulting atom-atom correlations. The quantum fields of both the molecules and atoms are simulated from first principles in three dimensions using the positive- P representation method. This allows us to provide an exact treatment of the molecular field depletion and s -wave scattering interactions between the particles, as well...[Show more]
