Classical-Wigner Phase Space Approximation to Cumulative Matrix Elements in Coherent Control
arXiv:physics/0305132 · doi:10.1063/1.1590962
Abstract
The classical limit of the Wigner-Weyl representation is used to approximate products of bound-continuum matrix elements that are fundamental to many coherent control computations. The range of utility of the method is quantified through an examination of model problems, single-channel Na_2 dissociation and multi-arrangement channel photodissociation of CH_2IBr. Very good agreement with the exact quantum results is found for a wide range of system parameters.
