(20.6) Because A transforms as a vector, the EM field is a vector field (in quantum mechanics this vector nature means ... (20.9) If the classical EM field is confined to a box of volume V, the most general field A is a linear combination of plane- wave solutions to the wave equation, that is, ... The field theory is equivalent, because (to quote Sakuraia#39;s paraphrase of Fermi) awe can forget about the dynamicalanbsp;...
