N2 - Upcoming and planned experiments combining increasingly intense lasers and energetic
particle beams will access new regimes of nonlinear, relativistic, quantum effects. This
improved experimental capability has driven substantial progress in QED in intense
background fields. We review here the advances made during the last decade, with
a focus on theory and phenomenology. As ever higher intensities are reached, it
becomes necessary to consider processes at higher orders in both the number of
scattered particles and the number of loops, and to account for non-perturbative
physics (e.g. the Schwinger effect), with extreme intensities requiring resummation of
the loop expansion. In addition to increased intensity, experiments will reach higher
accuracy, and these improvements are being matched by developments in theory such
as in approximation frameworks, the description of finite-size effects, and the range
of physical phenomena analysed. Topics on which there has been substantial progress
include: radiation reaction, spin and polarisation, nonlinear quantum vacuum effects and
connections to other fields including physics beyond the Standard Model.
