Query: Electron-Positron Pair Production in Structured Pulses of Electric
  Fields   The non-perturbative electron-positron pair production in time-dependent
electric fields is investigated. The quantum kinetic formalism is employed in
order to calculate the electron density for various field configurations. The
corresponding set of first order, ordinary differential equations is analyzed
and numerically solved. The focus of this study lies on the dynamically
assisted Schwinger effect in pulsed electric fields with at least two different
time scales. Furthermore, interference effects arising in setups with multiple
pulses are examined and first results for an optimization of the particle
number yield by pulse-shaping are given.
