  We present mean-field calculations of azimuthally averaged retarded
dipole-dipole interactions in a Bose-Einstein condensate induced by a laser, at
both long and short wavelengths. Our calculations demonstrate that
dipole-dipole interactions become significantly stronger at shorter
wavelengths, by as much as 30-fold, due to retardation effects. This
enhancement, along with inclusion of the dynamic polarizability, indicate a
method of inducing long-range interatomic interactions in neutral atom
condensates at significantly lower intensities than previously realized.
