Quantum and electrodynamics
This has been demonstrated in the famous Lamb-Retherford experiment and was the starting point for the development of the theory of Quantum electrodynamics ( which is able to deal with these vacuum fluctuations and employs the famous Feynman diagrams for approximations using perturbation theory ).
Quantum electrodynamics ( or " quantum electromagnetism "), which is currently ( in the perturbative regime at least ) the most accurately tested physical theory, < sup >( blog )</ sup > has been successfully merged with the weak nuclear force into the electroweak force and work is currently being done to merge the electroweak and strong force into the electrostrong force.
Quantum electrodynamics ( QED ) offers another derivation of the properties of a diffraction grating in terms of photons as particles ( at some level ).
Quantum electrodynamics and some branches of quantum theory also study and analyze electron superposition and other phenomena.
* 1948 – Richard Feynman, Julian Schwinger, Sin-Itiro Tomonaga and Freeman Dyson: Quantum electrodynamics
In his paper " The S-Matrix in Quantum electrodynamics ", Dyson derived relations between different S-matrix elements, or more specific " one-particle Green's functions ", in quantum electrodynamics, by summing up infinitely many Feynman diagrams, thus working in a perturbative approach.
