Phys. Rev. Lett. 88, 160402 (2002) [4 pages]Bose-Enhanced Chemistry: Amplification of Selectivity in the Dissociation of Molecular Bose-Einstein CondensatesReceived 11 December 2001; revised 15 March 2002; published 9 April 2002 We study the photodissociation chemistry of a quantum degenerate gas of bosonic triatomic ABC molecules, assuming two open rearrangement channels ( AB+C or A+BC). The equations of motion are equivalent to those of a parametric multimode laser, resulting in an exponential buildup of macroscopic mode populations. By exponentially amplifying a small differential in the single-particle rate coefficients, Bose stimulation leads to a nearly complete selectivity of the collective N-body process, indicating a novel type of ultraselective quantum degenerate chemistry. © 2002 The American Physical Society URL:
