Phys. Rev. Lett. 84, 5029–5033 (2000)Superchemistry: Dynamics of Coupled Atomic and Molecular Bose-Einstein CondensatesReceived 23 March 1999; revised 17 March 2000; published in the issue dated 29 May 2000 We analyze the dynamics of a dilute, trapped Bose-condensed atomic gas coupled to a diatomic molecular Bose gas by coherent Raman transitions. This system is shown to result in a new type of “superchemistry,” in which giant collective oscillations between the atomic and the molecular gas can occur. The phenomenon is caused by stimulated emission of bosonic atoms or molecules into their condensate phases. © 2000 The American Physical Society URL:
