Heating due to long-range photon exchange interactions between cold atoms.

Abstract:

We have calculated the long-range part of the momentum diffusion coefficient of two atoms in a radiation field using an S-matrix expansion to first order in the dipole-dipole interaction between the atoms. This perturbative treatment is limited to the low-saturation regime and large detunings. The physical processes arise from the interaction with the coherent and incoherent parts of the scattering spectrum. We find that in the regime of a constant density the extra diffusion term when averag...
