The calculation of rate coefficients is a discipline of nonlinear science of importance to much
of physics, chemistry, engineering, and biology. Fifty years after Kramers' seminal paper on …

This paper presents the results of a functional-integral approach to the dynamics of a two-
state system coupled to a dissipative environment. It is primarily an extended account of …

In the past ten years, the ideas of supersymmetry have been profitably applied to many
nonrelativistic quantum mechanical problems. In particular, there is now a much deeper …

It is shown that, in the context of an idealized ''macroscopic quantum coherence''experiment,
the predictions of quantum mechanics are incompatible with the conjunction of two general …

The quantum mechanical dynamics of a particle coupled to a heat bath is treated by
functional integral methods and a generalization of the Feynman-Vernon influence …

In biological and chemical electron transfer, a nuclear reaction coordinate is coupled to
other nuclear~ nd/or" solvent" coordinates. This coupling, or friction, if strong enough, may …

The quantum dynamics of tunnel junctions with very small capacitance, such that k BT< e
2/2C, is investigated. We derive the quantum mechanical description from the microscopic …

This paper reports the result of a calculation which shows the effect of damping on the
quantum interference of two Gaussian wave packets in a harmonic potential. We use the …

In this paper we present the results of a theoretical study of outer‐sphere electron transfer
(ET) in a polar solvent, with the modification of the nuclear states by the change in the …

Many important processes in science involve the escape of a particle over a barrier. In this
review, we report, extend, and interpret various theories of noise-activated escape. We …
