The Classical Limit of Quantum Theory - Werner (1995) (Correct)
....is concentrated on the classical orbits, and has the initial condition as the only random parameter. On the other hand, if we take h C, some quantum perturbations of the free evolution survive the limit, and we get a diffusion in phase space with diffusion constant proportional to C (compare [FLM] and with a drift given by the Hamiltonian vector field. Joint work on these issues is in progress with Fabio Benatti. 5) Higher orders in h In the WKB method one is usually not only interested in the classical limit, but in the asymptotic expansion of the wave functions to all orders in h. ....
