Collective coordinates as open systems. (II). Time-scale for pure-state propagation
In the frame of a general master equation, we investigate the condition for the propagation of pure-state wave packets conditioned to the gain-loss competition between the different components. If a perturbative approach is adopted, it is shown that the hamiltonian type of evolution is destroyed wit...
