Abstract
The quantum limits of stochastic cooling of trapped atoms are studied. The energy subtraction due to the applied feedback is shown to contain an additional noise term due to atom-number fluctuations in the feedback region. This effect is shown to dominate the cooling efficiency near the condensation point. Furthermore, we show results that indicate that Bose-Einstein condensation could be reached via stochastic cooling.
