Quantum Theory of Feedback of Bosonic Gases
arXiv:quant-ph/0203069 · doi:10.1103/PhysRevA.66.032114
Abstract
A quantum theory of feedback of bosonic many-atom systems is formulated. The feedback-induced many-atom correlations are treated by use of a parameterized correlation function, for which closed equations of motion are derived. Therefrom the dynamics of any additive property of the system, i.e., properties derived from the reduced single-atom density operator, can be obtained. An example is given that indicates the correlation effects of feedback.
