霍金辐射、手征性和有效引力理论的原理

Hawking radiation, chirality, and the principle of effective theory of gravity

Adamantia Zampeli, Douglas Singleton, Elias C. Vagenas

摘要:

本文将近视界区场论的手征性与有效引力理论的原理相结合,定义了一个新的有效引力理论的能量动量张量。这个新的能量-动量张量有正确的辐射通量来解释具有视界的时空中的霍金辐射。该方法与手征异常抵消方法相关联,但它适用于手征异常抵消方法失效的时空。特别地,这里提出的方法适用于非渐近平坦的de Sitter时空及其相关的Hawking-Gibbons辐射,以及Rindler时空及其相关的Unruh辐射。这表明,在近视界区,场论的手征性质才是最重要的,而不是手征反常。

英文摘要:

In this paper we combine the chirality of field theories in near horizon regions with the principle of effective theory of gravity to define a new energy-momentum tensor for the theory. This new energy-momentum tensor has the correct radiation flux to account for Hawking radiation for space-times with horizons. This method is connected to the chiral anomaly cancellation method, but it works for space-times for which the chiral anomaly cancellation method fails. In particular the method presented here works for the non-asymptotically flat de Sitter space-time and its associated Hawking-Gibbons radiation, as well as Rindler space-time and its associated Unruh radiation. This indicates that it is the chiral nature of the field theory in the near horizon regions which is of primary importance rather than the chiral anomaly.
