    "abstract": "We study the limitations to the relative number squeezing between photons and\natoms coupled out from a homogeneous Bose-Einstein-Condensate. We consider the\ncoupling between the translational atomic states by two photon Bragg processes,\nwith one of the photon modes involved in the Bragg process in a coherent state,\nand the other initially unpopulated. We start with an interacting Bose-\ncondensate at zero temperature and compute the time evolution for the system.\nWe study the squeezing, i.e. the variance of the occupation number difference\nbetween the second photon and the atomic c.m. mode. We discuss how collisions\nbetween the atoms and photon rescattering affect the degree of squeezing which\nmay be reached in such experiments.",
