The worldline formalism in strong-field QED
arXiv:2304.07404 · doi:10.1088/1742-6596/2494/1/012020
Abstract
The worldline formalism provides an alternative to Feynman diagrams that has been found particularly useful for external-field calculations in quantum electrodynamics. Here I summarize its present range of applications, which includes Schwinger pair creation, photon splitting in constant fields and plane-wave backgrounds, as well as nonlinear Compton scattering in constant fields.
