Title: Matter-wave amplification and phase conjugation via stimulated dissociation of a molecular Bose-Einstein condensate

Abstract

We propose a scheme for parametric amplification and phase conjugation of an atomic Bose-Einstein condensate (BEC) via stimulated dissociation of a BEC of molecular dimers consisting of bosonic atoms. This can potentially be realized via coherent Raman transitions or using a magnetic Feshbach resonance. We show that the interaction of a small incoming atomic BEC with a (stationary) molecular BEC can produce two counterpropagating atomic beams - an amplified atomic BEC and its phase-conjugate or 'time-reversed' replica. The two beams can possess strong quantum correlation in the relative particle number, with squeezed number-difference fluctuations.
