Collisional strong-field QED kinetic equations from first principles

Starting from nonequilibrium quantum field theory on a closed time path, we derive kinetic equations for the strong-field regime of quantum electrodynamics (QED) using a systematic expansion in the gauge coupling e The strong field regime is characterized by a large photon field of order \mathcal{O}(1/e) which is relevant for the description of, e.g., intense laser fields, the initial stages of off-central heavy ion collisions, and...
