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 …

Excitation energy transfer (EET) is fundamental to many processes in chemical and
biological systems and carries significant implications for the design of materials suitable for …

This is an overview of some of the important, challenging, and problematic issues in
contemporary electron transfer research. After a qualitative discussion of electron transfer, its …

In a recent Letter [Chem. Phys. Lett. 221, 482 (1994)], we demonstrated that the dynamics of
reduced density matrices for systems in contact with dissipative harmonic environments can …

In this chapter, the authors discuss their recent development of the ab initio multiple
spawning (AIMS) method which solves the elecronic and nuclear Schrödinger equations …

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

Nine formulations of nonrelativistic quantum mechanics are reviewed. These are the
wavefunction, matrix, path integral, phase space, density matrix, second quantization …

Feynman's influence functional that arises from many-particle environments is nonlocal in
time but the nonlocality has finite range, even at very low temperature. Use of our …

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 …

We present a new method for solving the Redfield equation, which describes the evolution
of the reduced density matrix of a multilevel quantum‐mechanical system interacting with a …
