The trident process in laser pulses
Victor Dinu, Greger Torgrimsson
We study the trident process in laser pulses. We provide exact numerical results for all contributions, including the difficult exchange term. We show that all terms are in general…

Approximating higher-order nonlinear QED processes with first-order building blocks
Victor Dinu, Greger Torgrimsson
Higher-order tree-level processes in strong laser fields, i.e. cascades, are in general extremely difficult to calculate, but in some regimes the dominant contribution comes from a…
