Time evolution of the QED vacuum in a uniform electric Field: Complete analytic solution by spinorial decomposition

Understand

Exact analytical solutions are presented for the time evolution of the density of pairs produced in the QED vacuum by a time-independent, uniform electric field.

• The mathematical tool used here to describe the pair production is the Dirac-Heisenberg-Wigner function introduced before [Phys.
