Abstract

In this paper we would like to discuss three different topics that we have worked on recently. In the second section we would like to discuss some aspects of (adiabatic) stabilization, addressing what we believe its mechanism to be, as well as some recent computations that we have carried out in order to examine whether the breakdown of the dipole approximation in strong fields could perhaps overcome stabilization. In the second section we would like to give a short account of a formalism that we have developed in order to be able to include correlation effects within the Floquet approximation treatment of two-electron atoms that ionize in strong, low frequency fields. In the final section, we would like to summarize our efforts to numerically integrate the time-dependent Schrödinger equation for a two-electron system subject to an intense pulse of laser light. These efforts are taking place on the massively parallel ‘Connection Machine’. Since massive parallelism, a new concept in supercomputing, has only made its entrance in atomic physics quite recently, we deem it worthwhile, without going into too much detail, to give a brief overview of some particular features of this machine and how one goes about developing efficient algorithms on it.

    The notion of stabilization was not new, see e.g. [8]. Although predicting ‘stabilization’ in very intense fields, it appears however that these findings were based on theories that were seriously in error.Google Scholar
