Coherent Processes in Atom in Strong Radiation Fields
Abstract
During this grant period work proceeded to study alternative methods of integrating the higher dimensional time-dependent partial differential equations that arise in the study of atoms interacting with intense laser radiation. Present methods use, for example, Taylor series propagators applied to finite-difference and basis set models. We have more recently developed modified propagators based on polynomial extrapolation, rational polynomial extrapolation (Buelisch-Stoer), and have prepared versions that can be effectively vectorized on Cray YMP computers, and in the case of polynomial extrapolation, parallelize on massively parallel computers. In addition, the stability and accuracy of the finite-difference models has been compared to those based on interpolatory splines. The main effort in this grant was directed toward developing numerical integrators for the Schroedinger equation describing the interaction on atoms with circularly polarized light.
