From local to nonlocal: higher fidelity simulations of photon emission in intense laser pulses
T. G. Blackburn, A. J. MacLeod, B. King
State-of-the-art numerical simulations of quantum electrodynamical (QED) processes in strong laser fields rely on a semiclassical combination of classical equations of motion and Q…
The locally monochromatic approximation to QED in intense laser fields
T. Heinzl, B. King, A. J. MacLeod
We derive an approximation to QED effects in strong background fields which can be employed to improve numerical simulations of laser-particle collisions. Treating the laser as a p…
Absorption cross section in an intense plane wave background
Anton Ilderton, Ben King, Alexander John Macleod
We consider the absorption of probe photons by electrons in the presence of an intense, pulsed, background field. Our analysis reveals an interplay between regularisation and gauge…
Cherenkov radiation from the quantum vacuum
Alexander J. Macleod, Adam Noble, Dino A. Jaroszynski
A charged particle moving through a medium emits Cherenkov radiation when its velocity exceeds the phase velocity of light in that medium. Under the influence of a strong electroma…
