    Abstract:

    A kinetic approach to scalar QED in a strong and time-dependent electric field is studied taking into account self-interactions. A quantum kinetic equation, including both a term describing crossed effects of vacuum particle creation and self-interaction in the Hartree-Fock approximation and a collision integral of Boltzmann type, is derived. The source term and collision integrals are characterized by a non-Markovian structure pointing to a complicated interplay of time scales in any realistic scenario.
