Description

Recently it has been found that the superposition of a strong and slow electric field with a weaker and faster electromagnetic pulse can significantly enhance the probability for non-perturbative electron-positron pair creation out of the vacuum — the dynamically assisted Sauter-Schwinger effect. After a brief introduction into the basics of this effect, this talk will be devoted to the dependence of this enhancement mechanism on momentum and the pulse shape as well as further developments.
