Also calculations using relativistic QED are difficult to perform, so they had been done to only the first order. Source: Internet

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

Dyson could show that a rescaling of charge and mass (‘renormalization’) is sufficient to remove all divergences in QED to all orders of perturbation theory. Source: Internet

Dirac's quantum electrodynamics (QED) made predictions that were – more often than not – infinite and therefore unacceptable. Source: Internet

E.g., section 10.1 in citation This concept is applied in key predictions of quantum electrodynamics (QED, see above). Source: Internet

As Weinberg points out the “photon is the only particle that was known as a field before it was detected as a particle” so that it is natural that QED began with the analysis of the radiation field. Source: Internet
