Description

The semiclassical approximation of the coherent-state propagator requires the computation of complex trajectories satisfying special boundary conditions. In this paper we present a method for the determination of such trajectories for one-dimensional polynomial potentials. We also compute the semiclassical propagator for the case V(q)=λq2/2+βq4 and compare the results with an open-quote open-quote exact close-quote close-quote calculation.
