摘要：
We find the exact dynamics - in mean value - for a particular model of the Schrodinger-Langevin equation that preserves norm for all realizations [J. Phys. A Math. Gen. 32 (1999) 631], Using Novikov's theorem we prove that the dynamics generated by a stochastic Gaussian Hamiltonian gives for the density matrix an evolution governed by a non-local in time Kossakowki-Lindblad like generator. This model can help to study dissipation and decoherence beyond the Markovian approximation. (C) 2001 Elsevier Science B.V. All rights reserved.
