Particle condensates in quantum field theory

Конденсаты частиц в квантовой теории поля

  • Published:
Il Nuovo Cimento A (1965-1970)

Summary

A general equivalence between functional techniques and canonical quantization for a simple self-interacting scalar theory is proposed. Vacuum instability for the symmetric (〈φ〉=0) and non-symmetric cases is analysed in detail.

Riassunto

In questo articolo si formula un’equivalenza generale tra tecniche funzionali e quantizzazione canonica in una semplice teoria scalare autointeragente. La stabilità del vuoto per casi simmetrici e non simmetrici è analizzata in dettaglio.

Резюме

Предполагается общая эквивалентность между функциональной техникой и каноническим квантованием для простой самовзаимодействующей скалярной теории. Подробно анализируется неустойчивость вакуума для симметричного (〈φ〉=0) и несимметричного случаев.
