Spontaneous pair creation in an electric field: A space-time analysis

Рпонтанное образование пар в электрическом поле: пространственно-временной анализ

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

The connection between Schwinger's proper-time and Feynman's path integral methods is exploited in order to obtain a space-time description of spontaneous pair creation in an external field. The relevance of classical closed trajectories in Euclidean space-time and the connection with the tunnel effect of nonrelativistic quantum mechanics are discussed.

Riassunto

Si esamina la connessione tra il metodo di Schwinger del tempo proprio e quello di Feynman dell'integrazione sui percorsi al fine di ottenere una descrizione spazio-temporale del processo di creazione spontanea di coppie in un campo esterno. Si discute l'analogia con l'effetto tunnel della meccanica quantistica non relativistica e si mette in evidenza l'importanza delle traiettorie class'che chiuse nello spazio-tempo euclideo.

Резюме

Чтобы получить пространственно-временное описание спонтанного образования пар во внешнем поле, используется связь между собственным временем Швингера и фейнмановским методом интегрирования по траекториям. Обсуждаются важность классических замкнутых траекторий в эвклидовом пространстве-времени и аналогия с туннельным эффектом нерелятивистской квантовой механики.
