Bose fields and inequivalent representations

  • S. Kamefuchi
  • H. Umezawa


The self-consistent method based on the inequivalent representations, which was developed for fermion fields in our previous paper, is now extended to boson fields. An application is also made to the Goldstone models. Our results seem to indicate that the Goldstone theorem does not always hold true in theories which make use of the self-consistent method.


Si estende ai campi di Bose il metodo autocoerente basato sulle rappresentazioni inequivalenti, che è stato sviluppato per i campi fermionici in un lavoro precedente. Se ne fa un’applicazione anche ai modelli di Goldstone. I nostri risultati sembrano indicare che il teorema di Goldstone non è sempre valido nelle teorie che fanno uso del metodo autocoerente.
