Hanbury Brown and Twiss correlations in atoms scattered from colliding condensates
arXiv:0710.0208 · doi:10.1103/PhysRevA.77.033601
Abstract
Low energy elastic scattering between clouds of Bose condensed atoms leads to the well known s-wave halo with atoms emerging in all directions from the collision zone. In this paper we discuss the emergence of Hanbury Brown and Twiss coincidences between atoms scattered in nearly parallel directions. We develop a simple model that explains the observations in terms of an interference involving two pairs of atoms each associated with the elementary s wave scattering process.
