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 …

The double copy is, in essence, a map between scattering amplitudes in a broad variety of
familiar field and string theories. In addition to the mathematically rich intrinsic structure, it …

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 …

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 …

We present a proposal for a cold copper distributed coupling accelerator that can provide a
rapid route to precision Higgs physics with a compact 8 km footprint. This proposal is based …

This article first gives the authors' perspectives on how the field of plasma-based
acceleration (PBA) developed and how the current experiments, theory, and simulations are …

Plasma current filamentation of an ultrarelativistic electron beam impinging on an overdense
plasma is investigated, with emphasis on radiation-induced electron polarization. Particle-in …

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 …
