Perturbative methods for assisted nonperturbative pair production
Greger Torgrimsson
In the dynamically assisted Schwinger mechanism, the pair production probability is significantly enhanced by including a weak, rapidly varying field in addition to a strong, slowl…

Single and double nonlinear Compton scattering
Victor Dinu, Greger Torgrimsson
We study single, double and higher-order nonlinear Compton scattering where an electron interacts nonlinearly with a high-intensity laser and emits one, two or more photons. We stu…

Discrete worldline instantons
Christian Schneider, Greger Torgrimsson, Ralf Schützhold
The semiclassical approximation of the worldline path integral is a powerful tool to study nonperturbative electron-positron pair creation in spacetime-dependent background fields.…
