Coherence refers to correlations in waves. Because matter has a wave-particle nature, it is
unsurprising that coherence has deep connections with the most contemporary issues in …

▪ Abstract Quantum-classical Liouville dynamics can be used to study the properties of open
quantum systems that are coupled to bath or environmental degrees of freedom whose …

We report a new method for calculating the Wigner transform of the Boltzmann operator in
the canonical ensemble. The transform is accomplished by writing the Boltzmann operator in …

Often quantum systems are not isolated and interactions with their environments must be
taken into account. In such open quantum systems these environmental interactions can …

▪ Abstract Quantum dissipation involves both energy relaxation and decoherence, leading
toward quantum thermal equilibrium. There are several theoretical prescriptions of quantum …

▪ Abstract This review describes some developments in the theory and application of the
semiclassical initial representation for the treatment of the dynamical and static properties of …

Quasi-classical map** Hamiltonian methods have recently emerged as a promising
approach for simulating electronically nonadiabatic molecular dynamics. The classical-like …

▪ Abstract Recent progress in the development of semiclassical methods to describe
quantum effects in molecular dynamics is reviewed. Focusing on rigorous semiclassical …

A general relationship is established between semiclassical and centroid-based methods for
calculating real-time quantum-mechanical correlation functions. It is first shown that the …
