Abstract

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.
