Upcoming and planned experiments combining increasingly intense lasers and energetic
particle beams will access new regimes of nonlinear, relativistic, quantum effects. This …

Report on progress in physics: observation of the Breit–Wheeler process and vacuum
birefringence in heavy-ion collisions - IOPscience Skip to content IOP Science home …

The Breit-Wheeler process which produces matter and antimatter from photon collisions is
experimentally investigated through the observation of 6085 exclusive electron-positron …

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

Various fundamental-physics experiments such as measurement of the magnetic
birefringence of the vacuum, searches for ultralight dark-matter particles (eg, axions), and …

interaction of an ultraintense laser pulse with a spin-polarized counterpropagating …

Abstract The Gamma Factory (GF) is an ambitious proposal, currently explored within the
CERN Physics Beyond Colliders program, for a source of photons with energies up to≈ 400 …

In a previous paper we showed how higher-order strong-field-QED processes in long laser
pulses can be approximated by multiplying sequences of'strong-field Mueller matrices'. We …

These notes provide a pedagogical introduction to the theoretical study of vacuum
polarization effects in strong electromagnetic fields as provided by state-of-the-art high …
