Abstract : This research program seeks to understand and control atomic collisions at ultracold temperatures where quantum and light-filed effects lead to new interactions between atoms. We have pursued experimental and theoretical investigations of optical shielding and suppression, and the nature of ground-state collisions in and near a Bose-Einstein condensate. This research shows how inelastic collisions can be turned on and turned off by light fields, how the scattering length of ultracold ground-state collisions might be altered by light fields.
