On the subsidiary condition in quantum electrodynamics

Dieter Maison, Daniel Zwanziger

    Research output: Contribution to journalArticlepeer-review


    It is proven that no charged state obtained by applying a local operator to the vacuum can satisfy the Gupta-Bleuler subsidiary condition. The meaning of this result is illustrated in the simple model whereby the vector potential is coupled to an external classical current. Alternative ways of handling the difficulty with the subsidiary condition are listed.
