Non-Markovian effects in strong-field pair creation

TLDR
In this paper, a quantum kinetic equation describing both boson and fermion pair production was analyzed and the solution of the non-Markovian kinetic equation was explored analytically and numerically.
Abstract
We analyze a quantum kinetic equation describing both boson and fermion pair production and explore analytically and numerically the solution of the non-Markovian kinetic equation. In the low density limit of the kinetic equation we find an analytical solution for the single particle distribution function of bosons and fermions. The numerical investigation for a homogeneous, constant electric field shows an enhancement (bosons) or a suppression (fermions) of the pair creation rate according to the symmetry character of the produced particles. For strong fields non-Markovian effects are important while they disappear for weak fields. Hence it is sufficient to apply the low density limit for weak fields but necessary to take into account memory effects for strong fields.

Pair production from vacuum at the focus of an X-ray free electron laser

TL;DR: In this paper, the authors discuss the possibility of obtaining an electric field so high that electron-positron pairs are spontaneously produced in vacuum (Schwinger pair production), and they find that if X-ray optics can be improved to approach the diffraction limit of focusing, and if the power of the planned Xray FELs can be increased to the terawatt region, then there is ample room for an investigation of the Schwinger Pair production mechanism.
