DESCRIPTION:Speakers: Matthias Diez (Graz U)\n\nStrong electromagnetic fie
 lds can destabilize the quantum vacuum and produce electron–positron pai
 rs through the Sauter–Schwinger effect. In this presentation I will expl
 ore pair production in time-dependent and spatially inhomogeneous fields u
 sing the Dirac–Heisenberg–Wigner formalism and quantum kinetic theory.
  Particular attention is paid to the interpretation of particle numbers at
  intermediate times and the emergence of characteristic temporal and spati
 al scales. Finally\, in the presentation I discuss how the induced current
  modifies the electromagnetic field through backreaction\, including curre
 nt renormalization and the emergence of plasma oscillations.\n\nhttps://in
