Abstract
We analyze the effects of atom-atom collisions on a collective laser cooling scheme. We derive a quantum master equation which describes the laser cooling in presence of atom-atom collisions in the weak-condensation regime. Using such equation, we perform Monte Carlo simulations of the population dynamics in one and three dimensions. We observe that the ground-state laser-induced condensation is maintained in the presence of collisions. Laser cooling causes a transition from a Bose-Einstein distribution describing collisionally induced equilibrium, to a distribution with an effective zero temperature. We analyze also the effects of atom-atom collisions on the cooling into an excited state of the trap.
