Compton scattering driven by intense quantum light.

The article presents a study which developed a framework to describe the nonperturbative interaction of a charged particle with driving fields of an arbitrary quantum light state. Topics discussed include nonperturbative interaction of matter with arbitrary light states in quantum electrodynamics (QED), the emission power spectrum of Compton scattering driven by arbitrary light states, and spectral broadening and higher harmonics induced by photon statistics.
