The quantum limits of stochastic cooling of trapped atoms are studied. Theenergy subtraction due to the applied feedback is shown to contain anadditional noise term due to atom-number fluctuations in the feedback region.This novel effect is shown to dominate the cooling efficiency near thecondensation point. Furthermore, we show first results that indicate thatBose--Einstein condensation could be reached via stochastic cooling.Comment: 5 pages, 3 figures, to appear in Phys. Rev.
