Confinement effects on the stimulated dissociation of molecular Bose-Einstein condensates Academic Article uri icon


  • We show that a molecular Bose-Einstein condensate in a trap is stabilized against stimulated dissociation if the trap size is smaller than the resonance healing length $({\ensuremath{\hbar}}^{2}/2mg\sqrt{n}{)}^{1/2}$. The condensate shape determines the critical atom-molecule coupling frequency. We discuss an experiment for triggering dissociation by a sudden change of coupling or trap parameters. This effect demonstrates one of the unique collective features of ``superchemistry'' in that the yield of a chemical reaction depends critically on the size and shape of the reaction vessel.
