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 …

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 …

We demonstrate the experimental feasibility of probing the fully nonperturbative regime of
quantum electrodynamics with a 100 GeV-class particle collider. By using tightly …

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 …

Light–matter interactions driven by ultrahigh-intensity lasers have great potential to uncover
the physics associated with quantum electrodynamics (QED) processes occurring in neutron …

The emission of light from charged particles underlies a wealth of scientific phenomena and
technological applications. Classical theory determines the emitted photon energy by …

The local-constant-field approximation (LCFA) is an essential theoretical tool for
investigating strong-field QED phenomena in background electromagnetic fields with …

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 …

A bstract We consider radiation emitted by colour-charged and massive particles crossing
strong plane wave backgrounds in gauge theory and gravity. These backgrounds are …
