Zusammenfassung:
The simultaneous creation of multiple electron-positron pairs by localized
strong electric fields is studied by utilizing a time- and space-resolved
quantum field theory approach. It is demonstrated that the number of
simultaneously created pairs equals the number of the potential's supercritical
quasibound states in the Dirac sea. This means it can be controlled by tuning
the potential parameters. Furthermore, the energy of the created particles
corresponds to the energy of the supercritical quasibound states. The
simultaneously created electrons and positrons are statistically correlated,
which is reflected in the spatial distribution and the momentum distribution of
these particles and antiparticles.
