WebIn Section 3.3.3, we consider a new class of four-component basis set that is consistent with the Furry picture, the charge-conjugation symmetries of the free-particle Dirac equation and the relativistic Gaussian basis set technologies that we have developed for molecular physics and quantum chemistry.
The laws of electromagnetism (both classical and quantum) are invariant under the exchange of electrical charges with their negatives. For the case of electrons and quarks, both of which are fundamental particle fermion fields, the single-particle field excitations are described by the Dirac equation One wishes to find a charge-conjugate solution
WebFeb 24, 2024 · The reasoning here, as I understand it, is that the charge conjugation operator is applied to a particular Dirac spinor (I think that's what you mean by "C-symmetry operation of Dirac spinor fields" ) rather than to all electrons. Since the electrons that create the electric and magnetic fields are left alone, so are the corresponding fields. business navigator nbWeb5.
