Symmetry restoration in conformally flat metrics

Восстановление симметрии в конформно плоской метрике

Summary

We study symmetry restoration in a curved-background metric. Massless scalar QED is considered in the de Sitter space-time. The radius of the cosmological-event horizon corresponding to the critical temperature turns out to be of the order of the Compton wave-length of the vector boson. Quite similarly, the Gross-Neveau model in the two-dimensional Schwarzschild background shows symmetry restoration when the radius of the black-hole horizon becomes comparable with the Compton wave-length of the spinor.

Riassunto

Si studia il ripristino di una simmetria in una metrica curva. Si considera la QED scalare a massa zero nello spazio-tempo di De Sitter. Il raggio dell'orizzonte d'eventi cosmologici corrispondente alla temperatura critica risulta dell'ordine di grandezza della lunghezza d'onda Compton del bosone vettore. In maniera del tutto simile il modello di Gross-Neveau nella metrica di Schwarzschild bidimensionale mostra un ripristino della simmetria quando il raggio dell'orizzonte del buco nero diventa confrontabile con la lunghezza d'onda Compton dello spinore.

Резюме

Мы исслрдуем восстановление симметрии в искривленной метрике фона. Рассматривается безмассовая скалярная квантовая электродинамика в пространстве—времени Де Ситтера. Радиус космологического горизонта событий, соответствующий критической температуре, оказывается равным по порядку величины комптоновской длине волны векторного бозона. По аналогии с моделью Гросса-Нево в двумерной метрике Шварцшильда демонстрируется восстановление симметрии, когда радиус горизонта черной дыры становится сравнимым с комптоновской длиной волны спинора.
