Photon polarisation in light-by-light scattering: finite size effects
Victor Dinu, Tom Heinzl, Anton Ilderton +2
We derive a simple expression for the photon helicity and polarisation-flip probabilities in arbitrary background fields, in the low energy regime. Taking the background to model a…

Vacuum refractive indices and helicity flip in strong-field QED
Victor Dinu, Tom Heinzl, Anton Ilderton +2
Vacuum birefringence is governed by the amplitude for a photon to flip helicity or polarisation state in an external field. Here we calculate the flip and non-flip amplitudes in ar…
