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.
