▪ Abstract This review focuses on time-dependent methods suitable for simulating the
quantum dynamics of processes in large clusters and condensed-phase environments. A …

In this review we discuss quantum dynamically based theoretical methods for studying
bimolecular gas phase chemical reactions. The scope is largely limited to reactions …

Quantum Dissipative Systems : Introduction Page 1 1 Introduction Quantum-statistical
mechanics is a very rich and checkered field. It is the theory dealing with the dynamical …

Recent progress in numerical methods for evaluating the real-time path integral in
dissipative harmonic environments is reviewed. Quasi-adiabatic propagators constructed …

We present accurate fully quantum calculations of thermal rate constants for a symmetric
double well system coupled to a dissipative bath. The calculations are performed using the …

The idea of using a good representation as the zeroth order description of a problem, which
is widely used in perturbation theory and in basis set calculations, is extended to the path …

Monte Carlo studies involving real time dynamics are severely restricted by the sign problem
that emerges from a highly oscillatory phase of the path integral. In this Letter, we present a …

The dynamics of spin-boson systems at very low temperatures has been studied using a real-
time path-integral simulation technique, which combines a stochastic Monte Carlo sampling …

A fully quantum mechanical methodology for simulating the time evolution of low-
dimensional systems in harmonic dissipative environments is presented. The key features of …

This article discusses the use of path integral techniques for the study of dynamical
processes in many-body quantum systems. Recently developed approaches are described …
