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

The dynamics of charged particles in electromagnetic fields is an essential component of
understanding the most extreme environments in our Universe. In electromagnetic fields of …

The field of laser-matter interaction traditionally deals with the response of atoms, molecules,
and plasmas to an external light wave. However, the recent sustained technological …

Abstract This Conceptual Design Report describes LUXE (Laser Und XFEL Experiment), an
experimental campaign that aims to combine the high-quality and high-energy electron …

In the calculation of probabilities of physical processes occurring in a background classical
field, the local-constant-field approximation (LCFA) relies on the possibility of neglecting the …

A detailed analysis of the photon emission spectra of an electron scattered by a laser pulse
containing only very few cycles of the carrying electromagnetic field is presented. The …

Strong background fields require a nonperturbative treatment, which is afforded in QED by
the Furry expansion of scattering amplitudes. It has been conjectured that this expansion …

Analytical calculations of radiative corrections in strong-field QED have hinted that in the
presence of an intense plane wave the effective coupling of the theory in the high-energy …

The scattering of temporally shaped intense laser pulses off electrons is discussed by
means of manifestly covariant quantum electrodynamics. We employ a framework based on …

We investigate quantum radiation reaction in laser-electron interactions across different
energy and intensity regimes. Using a fully quantum approach which also accounts exactly …
