Upcoming and planned experiments combining increasingly intense lasers and energetic
particle beams will access new regimes of nonlinear, relativistic, quantum effects. This …

We estimate the energy distribution of positrons produced in the interaction of ultrarelativistic
electrons with a high-intensity laser beam. The underlying trident process is factorized on …

In the quasistatic regimes of nonlinear Breit-Wheeler and trident pair creation, the rates can
exhibit a nonanalytic dependency on the fundamental coupling of quantum electrodynamics …

Inverse Compton scattering of ultra-relativistic electron beams in the field of a high-intensity
laser produces photon beams with angular and spectral distributions that are strongly …

Vortex pattern formation in electron-positron pair creation from vacuum by a time-dependent
electric field of linear polarization is analyzed. It is demonstrated that in such scenario the …

Suitably normalized differential probabilities of one-photon emission in external
electromagnetic fields are compared to quantify the transit of nonlinear Compton scattering …
