Atom-atom correlations and relative number squeezing in dissociation of spatially inhomogeneous molecular condensates

Ögren, Magnus LU and Kheruntsyan, K.V. (2008) In Physical Review A 78(1).
Abstract
We study atom-atom correlations and relative number squeezing in the dissociation of a Bose-Einstein condensate (BEC) of molecular dimers made of either bosonic or fermionic atom pairs. Our treatment addresses the role of the spatial inhomogeneity of the molecular BEC on the strength of correlations in the short time limit. We obtain explicit analytic results for the density-density correlation functions in momentum space, and show that the correlation widths and the degree of relative number squeezing are determined merely by the shape of the molecular condensate.
