Coherent interaction of light with single atoms and atomic ensembles under quantum degeneracy conditions (in Russian, based on the PhD thesis) 

This talk is based on my PhD thesis and consists of two major parts. The first one is devoted to the theory of light scattering from a Bose-Einstein condensate. The second one describes the Raman Sideband Cooling mechanism which we explored for a single atom in an optical dipole trap. We developed a theory allowing to lower the single atom energy till the ground one. This single atom is treated as a qubit in our MSU colleagues setup that is why this cooling mechanism is essential to reduce any deleterious effects related to the residual atomic motion in a dipole trap.
