临界引力中熵的面积定律

Area law of the entropy in the critical gravity

Edwin J. Son, Myungseok Eune, Wontae Kim

摘要:

在最近提出的四维临界引力中,Schwarzschild-anti de Sitter黑洞的熵在欧氏作用量公式中是微不足道的,而它是由t Hooft给出的砖墙方法中的面积定律表示的.为了解决这个问题,我们将欧几里德作用量公式与砖墙方法半经典地联系起来,证明了黑洞的熵在临界点可以用面积定律来表示。

英文摘要:

The entropy of the Schwarzschild-anti de Sitter black hole in the recently proposed four-dimensional critical gravity is trivial in the Euclidean action formulation, while it is expressed by the area law in terms of the brick wall method given by 't Hooft. To resolve this issue, we relate the Euclidean action formulation to the brick wall method semiclassically, and show that the entropy of the black hole can be expressed by the area law at the critical point.
