The vacuum polarization equation of state in quantum electrodynamics

Уравнение состояния с учетом поляризации вакуума в квантовой электроди намике

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

Summary

The problem of vacuum polarization is discussed with particular emphasis on the nature of logarithmic factors entering into the renormalization group equations for the quantum-electrodynamic equations of state. A vacuum magnetic instability is clearly indicated, which is also present in the anomalous magnetic moment of the electron.

Riassunto

Si discute il problema della polarizzazione nel vuoto con enfasi particolare sulla natura dei fattori logaritmici che entrano nelle equazioni di rinormalizzazione dei gruppi per le equazioni di stato dell’elettrodinamica quantistica. Si indica chiaramente l’instabilità magnetica nel vuoto, che è presente anche del momento magnetico anomalo dell’elettrone.

Резюме

Обсуждается проблем а поляризации вакуум а. Особое внимание уделяется природе ло гарифмических множи телей, которые входят в урав нения группы перенормиров ки для уравнений сост ояния в квантовой электроди намике. Отмечается магнитна я неустойчивость вак уума, которая также присутствует в аномальном магнитном моменте эл ектрона.
