Date (JST): Tue, Nov 22, 2011, 13:15 - 14:45
Place: Seminar Room A
Abstract: We here discuss the Stokes geometry for the Feynman propagator of a certain nonintegrable map. We first provide a brief review for virtual turning points and new Stokes curves that have been introduced as new notions in the exact WKB framework, and explain how to employ them to perform the saddle point evaluation of the quantum propagator. We also stress the importance of such a treatment in the issue of multi-dimensional quantum tunneling.
