Pair correlations of scattered atoms from two colliding Bose-Einstein Condensates: Perturbative Approach
arXiv:0807.3435 · doi:10.1103/PhysRevA.78.053605
Abstract
We apply an analytical model for anisotropic, colliding Bose-Einstein condensates in a spontaneous four wave mixing geometry to evaluate the second order correlation function of the field of scattered atoms. Our approach uses quantized scattering modes and the equivalent of a classical, undepleted pump approximation. Results to lowest order in perturbation theory are compared with a recent experiment and with other theoretical approaches.
