Title: "Photon-initiated processes at ATLAS”

Abstract: Maxwell's equations predict linear behaviour of light, but quantum electrodynamics allows for various non-linear 
phenomena including the scattering of photon pairs. I will present the landmark ATLAS study of light-by-light scattering 
and other effects including the elastic production of lepton pairs.
