Abstract

We consider the effect of long-range dipole-dipole interaction on the excitation exchange dynamics of cold two-level atomic gases in the conditions where the size of the atomic cloud is large as compared to the wavelength of the dipole transition. We show that this interaction results in population redistribution across the atomic cloud and in specific spectra of the spontaneous photons emitted at different angles with respect to the direction of atomic polarization.
