| Abstract: | We study a dynamical scheme for condensation of bosonic trapped gases beyond the Lamb-Dicke limit, when the photon-recoil
energy is larger than the energy spacing of the trap. Using quantum master equation formalism we demonstrate that dark-state
cooling methods similar to those designed for a single trapped atom allow for the condensation of a collection of bosons into
a single state of the trap, either the ground, or an excited state. By means of Monte-Carlo simulations we analyse the condensation
dynamics for different dimensions, and for different cooling schemes.
