By using a complex eld with a symmetric combination of electric and magnetic elds, a rstorder covariant Lagrangian for Maxwell's equations is obtained, similar to the Lagrangian for the Dirac equation. This leads to a dual-symmetric quantum electrodynamic theory with an in nite set of local conservation laws. The dual symmetry is shown to correspond to a helical phase, conjugate to the conserve...
The typical values of R = quantum energy/potential amplitude in electron energy of an incident radiation treated in quantum electrodynamics, an electric wiggler, and a magnetic wiggler are 108, 10–4 and 10–10, respectively. Therefore, the interaction of a free electron with these fields cannot be described with the same principle. The wave-function phase of the final state through a transition ...
