摘要：

The Quantum Master Equation is derived by generalizing the van Kampen method. Starting with a stochastic Schrodinger equation and taking into account the finite quantum correlation-time of the thermal bath, Re have proved a Fluctuation-Dissipation like I elation, which preserves normalization on p. A tight-binding like hamiltonian in interaction with a phonon bath has been worked out within our approach. The continuous limits is also studied. (C) 1997 Elsevier Science B.V.
