Abstract

We discuss semiclassical and high-temperature expansions for the off-diagonal thermal kernel of quantum systems with non-uniform, time- In particular, we give an equation for the WKB-approxi- mation for such systems. Furthermore, we provide recursion relations and an efficient diagrammatic method, based on functional integration techniques,to calculate explicitly the coefficients in these expansions. Finally, we briefly indicate the connection between the semiclassical and high-temperature expansions.

Seminar given at the XXIII. Internationale Universitätswochen für Kernphysik, Schladming, Austria, February 20-March 1, 1984.
