Dynamically assisted Sauter-Schwinger effect---from nonperturbative to perturbative — Greger Torgrimsson, •Christian Schneider, and Ralf Schützhold — Fakultät für Physik, Universität Duisburg-Essen
The dynamically assisted Sauter-Schwinger effect is a tremendous increase in the probability of nonperturbative pair creation by the combination of a strong electric field and a weak, time dependent one. Especially the very sensitive dependence on the exact field profile of the weak pulse has not yet been fully understood. We present both detailed numerical data and new analytical results that agree remarkably well, allowing us to explain how these differences arise.
