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 …

We review common extensions of particle-in-cell (PIC) schemes which account for strong
field phenomena in laser-plasma interactions. After describing the physical processes of …

Electron–photon scattering, or Thomson scattering, is one of the most fundamental
mechanisms in electrodynamics, underlying laboratory and astrophysical sources of high …

The locally constant field approximation (LCFA) has to date underpinned the numerical
simulation of quantum processes in laser-plasma physics and astrophysics, but its validity …

A detailed analysis of the photon emission spectra of an electron scattered by a laser pulse
containing only very few cycles of the carrying electromagnetic field is presented. The …

The scattering of temporally shaped intense laser pulses off electrons is discussed by
means of manifestly covariant quantum electrodynamics. We employ a framework based on …

Strong background fields require a nonperturbative treatment, which is afforded in QED by
the Furry expansion of scattering amplitudes. It has been conjectured that this expansion …

We derive an approximation to QED effects in intense laser fields which can be employed in
laser-particle collisions. Treating the laser as a plane wave of arbitrary intensity, we split the …

We investigate the phenomenology of nonlinear Compton scattering of polarized photons by
unpolarized electrons in plane-wave backgrounds. The energy and angular spectra of …

We test current numerical implementations of laser-matter interactions by comparison with
exact analytical results. Focusing on photon emission processes, it is found that the …
