Reduced system dynamics from the N-body Schrodinger equation.
摘要：
We derive the time-dependent wave function for one particle in the company of N 1 other particles using the method of iterated projection. Using this approach, we confirm the general philosophy of describing a quantum system by a flow component and another component which may be given various descriptions as stochastic, heat bath, or quantum jump processes. The possible equivalence of the Breuer-Petruccione reduced system dynamics [Phys. Rev. Lett. 74 , 3788 (1995)] and ours is explored.
