a relativistic quantum theory of the electromagnetic interactions of photons and electrons and muons
Source: WordNetThe theory of quantum electrodynamics describes Nature as absurd from the point of view of common sense. And it agrees fully with experiment. So I hope you accept Nature as She is - absurd. Richard Feynman
Definition Quantum electrodynamics (QED) has one electron field and one photon field; quantum chromodynamics (QCD) has one field for each type of quark ; and, in condensed matter, there is an atomic displacement field that gives rise to phonon particles. Source: Internet
Quantum electrodynamics (QED) offers another derivation of the properties of a diffraction grating in terms of photons as particles (at some level). Source: Internet
