On time-dependent resonances for the Dirac equation and their adiabatic behavior — •Nikodem Szpak — Fakultät für Physik, Universität Duisburg-Essen

Studying spontaneous particle creation in strong external (electromagnetic) fields of QED we face the problem of description of the time-dependent resonances for the Dirac equation and the lack of adiabatic theorems for such systems. We present our analytical and numerical approaches to this problem as well as concepts developed on the way to formulation of the corresponding adiabatic theorems.
