Excess noise depletion of a Bose-Einstein condensate in an optical cavity
arXiv:0809.1984 · doi:10.1103/PhysRevLett.102.080401
Abstract
Quantum fluctuations of a cavity field coupled into the motion of ultracold bosons can be strongly amplified by a mechanism analogous to the Petermann excess noise factor in lasers with unstable cavities. For a Bose-Einstein condensate in a stable optical resonator, the excess noise effect amounts to a significant depletion on long timescales.
