Strong-field vacuum polarisation with high energy lasers
A. J. Macleod, J. P. Edwards, T. Heinzl +2
When photons propagate in vacuum they may fluctuate into matter pairs thus allowing the vacuum to be polarised. This linear effect leads to charge screening and renormalisation. Wh…
All-optical nonlinear Breit-Wheeler pair production with -flash photons
Alexander J. MacLeod, Prokopis Hadjisolomou, Tae Moon Jeong +1
High-power laser facilities give experimental access to fundamental strong-field quantum electrodynamics processes. A key effect to be explored is the nonlinear Breit-Wheeler proce…
From theory to precision modelling of strong-field QED in the transition regime
Alexander J. Macleod
The combination of energetic electron beams, delivered from conventional accelerators at a high repetition rate, and ultraintense lasers, makes it possible to perform precision mea…
Particle-beam scattering from strong-field QED
Tim Adamo, Anton Ilderton, Alexander J. MacLeod
We consider the scattering of probe particles on an ultra-boosted beam of charge, in the case that the fields of the beam are strong and must be treated non-perturbatively. We show…
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…
