Forward-backward semiclassical

K. Thompson and N. Makri. Rigorous forward-backward semiclassical formulation of many-body dynamics. Phys. Rev. E, 59(5) R4729-R4732, 1999. [Pg.413]

Fortunately, progress can be made because the Heisenberg operator involved in the evolution of time correlation functions or the quantum mechanical density matrix involves not only the forward time evolution operator but also its inverse. It is well understood that a dramatic phase cancellation takes place between these two propagation steps upon integration, and this cancellation is entirely responsible for the failure of Monte Carlo methods. To remedy this situation, Mgtoi and Thompson proposed a forward-backward semiclassical approximation (36) in which the time evolution operator and its inverse are combined into a single semiclassical treatment. This procedure is equivalent to a sta-... [Pg.403]
