Barrier penetration via path integrals

Barry R. Holstein, Arthur R. Swift

Published Sep 1, 1982• 34 citations
Publisher

Abstract

Path integral methods are applied to the problem of barrier penetration. By an excursion into complex time it is shown how the ideal of a ’’classical’’ path may be generalized to give a simple geometrical derivation of the usual WKB formulas.

Complex Time, Contour Independent Path Integrals, and Barrier Penetration

David W. McLaughlin

By developing an analogy between the Feynman path integral and contour integral representations of the special functions, we obtain WKB formulas for barrier penetration from a path integral. We first show that there exists for the path integral a notion of contour independence in the time parameter. We then select an appropriate contour to describe the physical situation of barrier penetration and obtain asymptotic formulas from the function space integral. The method is interpreted as a path integral derivation of the complex ray description of barrier penetration. In the last three sections we investigate several canonical problems of the theory of complex rays with these path integral techniques.

Tunneling, Stochastic Quantization, and Escape over a Barrier

David Leo Weaver

It is shown that quantum mechanical barrier penetration (tunneling) is related to classical escape over a related potential barrier, and that therefore the WKB approximation for the former and Kramers approximation for the latter are equivalent.
