Dynamically assisted Sauter-Schwinger effect - non-perturbative versus perturbative aspects
Greger Torgrimsson, Christian Schneider, Johannes Oertel +1
The Sauter-Schwinger effect predicts the creation of electron-positron pairs out of the quantum vacuum by a strong and slowly varying electric field. This effect can be dynamically…
Doubly assisted Sauter-Schwinger effect
Greger Torgrimsson, Johannes Oertel, Ralf Schützhold
We study electron-positron pair creation by a strong and slowly varying electric field, assisted by a weaker and more rapidly changing field (e.g., in the keV regime) plus an addit…
WKB approach to pair creation in spacetime-dependent fields
Johannes Oertel, Ralf Schützhold
Besides tunneling in static potential landscapes, for example, the Wentzel-Kramers-Brillouin (WKB) approach is a powerful nonperturbative approximation tool to study particle creat…
Inverse approach to solutions of the Dirac equation for space-time dependent fields
Johannes Oertel, Ralf Schützhold
Exact solutions of the Dirac equation in external electromagnetic background fields are very helpful for understanding non-perturbative phenomena in quantum electrodynamics (QED).…
