Stabilizing an atom laser using spatially selective pumping and feedback
arXiv:quant-ph/0501101 · doi:10.1103/PhysRevA.72.053603
Abstract
We perform a comprehensive study of stability of a pumped atom laser in the presence of pumping, damping and outcoupling. We also introduce a realistic feedback scheme to improve stability by extracting energy from the condensate and determine its effectiveness. We find that while the feedback scheme is highly efficient in reducing condensate fluctuations, it usually does not alter the stability class of a particular set of pumping, damping and outcoupling parameters.
