Non-perturbative signatures of non-linear Compton scattering
Uwe Hernandez Acosta, Andreas Otto, Burkhard Kämpfer +1
The probabilities of various elementary laser - photon - electron/positron interactions display in selected phase space and parameter regions typical non-perturbative dependencies…
Response of the QED(2) Vacuum to a Quench: Long-term Oscillations of the Electric Field and the Pair Creation Rate
A. Otto, D. Graeveling, B. Kämpfer
We consider -- within QED(2) -- the backreaction to the Schwinger pair creation in a time dependent, spatially homogeneous electric field. Our focus is the depletion of the externa…
Laser assisted Breit-Wheeler and Schwinger processes
T. Nousch, A. Otto, D. Seipt +5
The assistance of an intense optical laser pulse on electron-positron pair production by the Breit-Wheeler and Schwinger processes in XFEL fields is analyzed. The impact of a laser…
Pair production by Schwinger and Breit-Wheeler processes in bi-frequent fields
A. Otto, T. Nousch, D. Seipt B. Kämpfer +4
Counter-propagating and suitably polarized light (laser) beams can provide conditions for pair production. Here, we consider in more detail the following two situations: (i) In the…
Dynamical Schwinger process in a bifrequent electric field of finite duration: survey on amplification
Andreas Otto, Daniel Seipt, David Blaschke +2
The electron-positron pair production due to the dynamical Schwinger process in a slowly oscillating strong electric field is enhanced by the superposition of a rapidly oscillating…
