A wave function approach to dissipative processes
Yvan Castin, Jean Dalibard, Klaus Mølmer · AIP conference proceedings · 1993
We present a wave function approach to study the evolution of a small system when it is coupled to a large reservoir. Fluctuations and dissipation original in this approach from quantum jumps occurring randomly during the time evolution of the system. This approach can be applied to a wide class of relaxation operators in the Markovian regime, and it is equivalent to the standard Master Equation approach.
