Quantum Dynamics With Classical and Quantum Trajectories
The forward-backward semiclassical dynamics (FBSD) approximation provides a rigorous and practically useful methodology for simulating the dynamics of condensed phase systems that exhibit quantum mechanical effects. It is shown that FBSD autocorrelation functions of momentum and position-dependent …

Theoretical methods for the study of quantum dynamics
… mechanics. The convergence of the approximate forward-backward semiclassical dynamics (FBSD) method has been accelerated by working with only the imaginary part of the real-time position and momentum time correlation functions. Simple manipulations allow the computationally favorable limit of a …

Forward-Backward Methods for Mixed System Dynamics
… and computational efficiency in the study of its dynamics by applying mixed methods---methods that treat the two subsystems differently. In particular, the observable system is treated by a method that fully preserves its quantum character, while the treatment of its environment, the bath, …
