Key findings
Proposes a comprehensive program to develop a rigorous scattering theory for multi-electron atoms in massless QED.
Synthesizes Furry picture with modern infrared-safe dressing techniques and Bethe-Salpeter formalism.
Aims to provide a foundation for high-precision calculations of electron-atom and photon-atom scattering processes.
Limitations & open questions
The computational complexity of including all QED effects for atoms with three or more electrons remains prohibitive.
