Lightfront DHW Functions and Strong Field QED

Abstract [en]

We investigate strong-field effects in QED using a phase space approach based on the Dirac-Heisenberg-Wiger function. We calculate the electron-positron DHW function in a null (laser) field background exactly, using lightfront field theory. The DHW function exhibits the distinct features of strong-field QED: in particular we explicitly identify the effective fermion mass for arbitrary temporal pulse profiles.
