  We study a gaseous Bose-Einstein condensate with laser-induced dipole-dipole
interactions using the Hartree-Fock-Bogoliubov theory within the Popov
approximation. The dipolar interactions introduce long-range atom-atom
correlations, which manifest themselves as increased depletion at momenta
similar to that of the laser wavelength, as well as a "roton" dip in the
excitation spectrum. Surprisingly, the roton dip and the corresponding peak in
the depletion are enhanced by raising the temperature above absolute zero.
