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

The field of laser-matter interaction traditionally deals with the response of atoms, molecules,
and plasmas to an external light wave. However, the recent sustained technological …

Strong-field effects in laboratory and astrophysical plasmas and high intensity laser and
cavity systems are considered, related to quantum electrodynamical (QED) photon-photon …

Elastic light-by-light scattering (γ γ→ γ γ) is open to study at the Large Hadron Collider
thanks to the large quasireal photon fluxes available in electromagnetic interactions of …

When exposed to intense electromagnetic fields, the quantum vacuum is expected to exhibit
properties of a polarizable medium akin to a weakly nonlinear dielectric material. Various …

In this report we show that a vacuum is a nonlinear optical medium and discuss what the
optical phenomena are that should exist in the framework of the standard model of particle …

ELI-NP facility will enable for the first time the use of two 10 PW laser beams for quantum
electrodynamics (QED) experiments. The first beam will accelerate electrons to relativistic …

Vacuum birefringence is governed by the amplitude for a photon to flip helicity or
polarization state in an external field. Here, we calculate the flip and nonflip amplitudes in …

The nonlinear quantum interaction of a linearly polarized x-ray probe beam with a focused
intense standing laser wave is studied theoretically. Because of the tight focusing of the …

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 …
