Relativistic quantum kinetic theory: Higher order contributions in assisted Schwinger pair production

Quantum kinetic theory is an important tool for studying nonequilibrium, nonperturbative and nonlinear interactions within an open quantum system, and as such is able to provide an unprecedented view on particle production in the relativistic, ultrahigh intensity regime of quantum electrodynamics. By reorganizing the relativistic quantum transport equations for Abelian plasmas and integrating them with a perturbative expansion, we significantly expand the scope for kinetic theories to further elucidate the peculiarities of particle production at a spectral level.
