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 …

We review common extensions of particle-in-cell (PIC) schemes which account for strong
field phenomena in laser-plasma interactions. After describing the physical processes of …

Electron–photon scattering, or Thomson scattering, is one of the most fundamental
mechanisms in electrodynamics, underlying laboratory and astrophysical sources of high …

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 …

The locally constant field approximation (LCFA) has to date underpinned the numerical
simulation of quantum processes in laser-plasma physics and astrophysics, but its validity …

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 …

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 …

We derive an approximation to QED effects in intense laser fields which can be employed in
laser-particle collisions. Treating the laser as a plane wave of arbitrary intensity, we split the …

Abstract This Technical Design Report presents a detailed description of all aspects of the
LUXE (Laser Und XFEL Experiment), an experiment that will combine the high-quality and …
