Abstract:

We examine the time evolution of an object coupled to a heat reservoir at zero temperature in the framework of general master and kinetic equations for open systems. As we specialize to the particular set of solutions that represents pure states, we are led to a frictional Schrödinger equation that is free from either heuristic hypotheses or perturbation-like approximations. The generator of the evolution of damped pure states, namely the frictional hamiltonian. can be seen to be non-hermitian and to satisfy an integral, non-linear equation. The Schrödinger equation for damped wave packets is valid at all times, provided that a strongly restrictive condition holds. This condition offers an interesting interpretation in the general case. while in the weak-coupling limit, it could be said to provide a quantal version of a fluctuation-dissipation theorem. © 1981.
