Title: Evaluation Of The Semiclassical Coherent State Propagator In The Presence Of Phase Space Caustics
Author: Ribeiro A.D.
De Aguiar M.Am.
Abstract: A uniform approximation for the coherent state propagator, valid in the vicinity of phase space caustics, was recently obtained using the Maslov method combined with a dual representation for coherent states. In this paper we review the derivation of this formula and apply it to two model systems: the one-dimensional quartic oscillator and a two-dimensional chaotic system. © 2008 IOP Publishing Ltd.
