Sauter-Schwinger effect for colliding laser pulses
Christian Kohlfürst, Naser Ahmadiniaz, Johannes Oertel +1
Via a combination of analytical and numerical methods, we study electron-positron pair creation by the electromagnetic field of two…
Triplet Lifetime in Gaseous Argon
Michael Akashi-Ronquest, Amanda Bacon, Christopher Benson +27
MiniCLEAN is a single-phase liquid argon dark matter experiment. During the initial cooling phase, impurities within the cold gas (140 K) were monitored by measuring the scintil…
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).…
Update on the MiniCLEAN Dark Matter Experiment
K. Rielage, M. Akashi-Ronquest, M. Bodmer +43
The direct search for dark matter is entering a period of increased sensitivity to the hypothetical Weakly Interacting Massive Particle (WIMP). One such technology that is being ex…
