Phase space evolution of pairs created in strong electric fields
  We study the process of energy conversion from overcritical electric field
into electron-positron-photon plasma. We solve numerically Vlasov-Boltzmann
equations for pairs and photons assuming the system to be homogeneous and
anisotropic. All the 2-particle QED interactions between pairs and photons are
described by collision terms. We evidence several epochs of this energy
conversion, each of them associated to a specific physical process. Firstly
pair creation occurs, secondly back reaction results in plasma oscillations.
Thirdly photons are produced by electron-positron annihilation. Finally
particle interactions lead to completely equilibrated thermal
electron-positron-photon plasma.
