@article{Lindblad1998BrownianMO, title={Brownian motion of quantum harmonic oscillators: Existence of a subdynamics}, author={G{\"o}ran Lindblad}, journal={Journal of Mathematical Physics}, year={1998}, volume={39}, pages={2763-2780} }

The effects of system-environment correlations on the dynamics of an open quantum system are investigated for the standard model of a set of quantum harmonic oscillators interacting with a heat bath of oscillators. By definition, a subdynamics is described by transformations of the open system observables. It is shown that such a construction can reproduce the observable properties of the exact dynamics only when the states of system and environment are uncorrelated, while for classical systems…
