On the kinetic equation approach to pair production by time-dependent electric field
arXiv:1008.2098 · doi:10.1103/PhysRevD.83.025011
Abstract
We investigate the quantum kinetic approach to pair production from vacuum by time-dependent electric field. Equivalence between this approach and the more familiar S-matrix approach is explicitly established for both scalar and fermion cases. For the particular case of a constant electric field exact solution for kinetic equations is provided and the accuracy of low-density approximation is estimated.
