《万有引力之虹》中的黑环
Remnants of Black Rings from Gravity's Rainbow
摘要：
在本文中，我们研究了引力彩虹背景下的自旋黑环和带电黑环。通过将Amelino-Camelia等人在[arXiv：hep-th/9605211，arXiv：0806.0339v2]中提出的彩虹函数引入到黑环的度规中，它们的物理性质发生了相当大的修改。我们计算修正的温度，熵和热容量的黑环。这些计算表明，霍金辐射的行为在引力彩虹中的普朗克尺度附近发生了相当大的变化，其中表明黑环没有完全蒸发，并且当黑环蒸发到普朗克尺度时留下了残留物。
英文摘要：
In this paper, we investigate a spinning black ring and a charged black ring in the context of gravity's rainbow. By incorporating rainbow functions proposed by Amelino-Camelia, et al. in [arXiv:hep-th/9605211, arXiv:0806.0339v2] in the metric of the black rings, a considerable modification happens to their thermodynamical properties. We calculate corrections to the temperature, entropy and heat capacity of the black rings. These calculations demonstrate that the behavior of Hawking radiation changes considerably near the Planck scale in gravity's rainbow, where it is shown that black rings do not evaporate completely and a remnant is left as the black rings evaporate down to Planck scale.
