Fluctuation-dissipation relations for continuous quantum measurements
arXiv:cond-mat/0501630
Abstract
The generating functional is derived for the fluctuation-dissipation relations which result from the unitarity and reversibility of microscopic dynamics and connect various statistical characteristics of many consecutive (continuous) observations in a quantum system subjected to external perturbations. Consequences of these relations in respect to the earlier suggested stochastic representation of interaction between two systems are considered.
