Summary
In order to investigate the Gupta-Bleuler theory of the quantum electrodynamics from another point of view, one method is given which transforms the conventional metric to a new tensor byR-matrix and allows a canonical formalism that avoids the difficulty of making the momentum of the scalar photon identically vanish. As a consequence a general eigenstate of the pure radiation field is given in contrast to Gupta-Bleuler's. The expectation value of the subsidiary condition for the ghost state, corresponding to the Lorentz condition in the classical theory, vanishes.
Riassunto
Per studiare la teoria di Gupta-Bleuler dell'elettrodinamica quantistica da un altro punto di vista, si dà un metodo che trasforma la metrica convenzionale in un nuovo tensore mediante matriceR e permette un formalismo canonico che evita la difficoltà di annullare identicamente l'impulso del fotone scalare. Come conseguenza, si dà un autostato generale del puro campo di radiazione in contrasto con la teoria di Gupta-sponde alla condizione di Lorentz nella teoria classica, si annulla.
