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 …

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 …

By considering radiative corrections of up to 3rd-loop order, Ritus and Narozhny conjectured
that the proper expansion parameter for QED in a strong constant crossed field is g= α χ 2/3 …

QED perturbation theory has been conjectured to break down in sufficiently strong
backgrounds, obstructing the analysis of strong-field physics. We show that the breakdown …

We propose a scheme to explore regimes of strong-field quantum electrodynamics (SF
QED) otherwise unattainable with the currently available laser technology. The scheme …

Ongoing progress in laser and accelerator technology opens new possibilities in high-field
science, notably to investigate the largely unexplored strong-field quantum electrodynamics …

The scientific community is currently witnessing an expensive and worldwide race to
achieve the highest possible light intensity. Within the next decade this effort is expected to …

Electron beam longitudinal polarization during the interaction with counterpropagating
circularly polarized ultraintense laser pulses is investigated, while accounting for the …

The availability of ever stronger, laser-generated electromagnetic fields underpins
continuing progress in the study and application of nonlinear phenomena in basic physical …
