Prefactor in the dynamically assisted Sauter-Schwinger effect — •Christian Schneider and Ralf Schützhold — Universität Duisburg-Essen
The dynamically assisted Sauter-Schwinger effect exhibits significant, qualitative differences between, for example, a Sauter pulse 1/cosh(ω t)2 and a Gaussian exp(−ω2 t2) [1]. So far, only the exponent of the pair creation rate has been calculated, these results are now extended to include the subleading fluctuation prefactor.
Additionally, possible influences of spatial inhomogeneities are discussed. For example, a longitudinal spatial dependence modifies the exponent of the pair production probability [2], while a transversal dependence only affects the prefactor.
