Pair Production in Circularly Polarized Waves
Christian Kohlfürst
We study electron-positron pair production within two counter-propagating, circularly polarized electromagnetic fields through the Wigner formalism. We numerically generate high-re…
Dynamically assisted tunneling in the impulse regime
Christian Kohlfürst, Friedemann Queisser, Ralf Schützhold
We study the enhancement of tunneling through a potential barrier by a time-dependent electric field with special emphasis on pulse-shaped vector potentials such as $A_x(t)=…
Pair production in temporally and spatially oscillating fields
Ivan A. Aleksandrov, Christian Kohlfürst
Electron-positron pair production for inhomogeneous electric and magnetic fields oscillating in space and time is investigated. By employing accurate numerical methods (Furry-pictu…
Photon-Photon Scattering at the High-Intensity Frontier: Paraxial Beams
Alexander Blinne, Holger Gies, Felix Karbstein +2
Our goal is to study optical signatures of quantum vacuum nonlinearities in strong macroscopic electromagnetic fields provided by high-intensity laser beams. The vacuum emission sc…
