Random scattering by atomic density fluctuations in optical lattices.

We investigate hitherto unexplored regimes of probe scattering by atoms trapped in optical lattices: weak scattering by effectively random atomic density distributions and multiple scattering by arbitrary atomic distributions. Both regimes are predicted to exhibit a universal semicircular scattering line shape for large density fluctuations, which depend on temperature and quantum statistics.

Bose-Einstein condensates with 1/r interatomic attraction: electromagnetically induced "gravity".

We show that particular configurations of intense off-resonant laser beams can give rise to an attractive 1/r interatomic potential between atoms located well within the laser wavelength. Such a "gravitational-like" interaction is shown to give stable Bose-Einstein condensates that are self-bound (without an additional trap) with unique scaling properties and measurably distinct signatures.
