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 …

Charged particles accelerated by electromagnetic fields emit radiation, which must, by the
conservation of momentum, exert a recoil on the emitting particle. The force of this recoil …

Spin polarization of an ultrarelativistic electron beam head-on colliding with an ultraintense
laser pulse is investigated in the quantum radiation-dominated regime. We develop a Monte …

Since the invention of chirped pulse amplification, which was recognized by a Nobel Prize in
physics in 2018, there has been a continuing increase in available laser intensity. Combined …

Generation of circularly polarized (CP) and linearly polarized (LP) γ rays via the single-shot
interaction of an ultraintense laser pulse with a spin-polarized counterpropagating …

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 …

The generation of ultrarelativistic polarized positrons during the interaction of an
ultrarelativistic electron beam with a counterpropagating two-color petawatt laser pulse is …
