Time-Dependent Projection-Operator Techniques in Quantum Optics
We wish to describe the applications in quantum optics of a systematic approach to the analysis of coupled systems. This approach enables one to treat the coupled systems on an equal footing without assuming that any part of the system is large and reservoir-like. In the Schrödinger picture this approach leads to a description of the system in terms of exact generalized master equations (ME’s) which are obtained by operating on the quantum Liouville equation with a time-dependent projection operator (TDPO).
