黑洞熵的准正规模量子化

Quantization of Black Hole Entropy from Quasinormal Modes

Shao-Wen Wei, Ran Li, Yu-Xiao Liu, Ji-Rong Ren

摘要:

在Phys. Rev. D 78(2008)104018 [arXiv:0807.1481]中,Kothawala,Padmanabhan和Sarkar首先提出了“GB黑洞的熵本征值是离散的且等间距的,但面积间距不是等间距的”的结论。本文利用Maggiore提出的准正规模的新物理解释,计算了各种类型的不带电荷的非旋转黑洞的熵量子谱。通过对绝热不变量施加玻尔-索末菲量子化条件得到了谱。我们猜想熵谱的间距是等距离的,并且与时空的维数无关。但是,面积谱的间距取决于重力理论。在爱因斯坦的引力中,它是等距的,否则它是非等距的。这个猜想与Kothawala,Padmanabhan和Sarkar的结果一致。

英文摘要:

In Phys. Rev. D 78 (2008) 104018 [arXiv:0807.1481], the conclusion that "entropy eigenvalues of GB black hole are discrete and equally spaced, but the area spacing is not equidistant" was firstly presented by Kothawala, Padmanabhan and Sarkar. In this paper, using the new physical interpretation of quasinormal modes proposed by Maggiore, we calculate the quantum spectra of entropy for various types of non-rotating black holes with no charge. The spectrum is obtained by imposing Bohr-Sommerfeld quantization condition to the adiabatic invariant quantity. We conjecture that the spacing of entropy spectrum is equidistant and is independent of the dimension of spacetime. However, the spacing of area spectrum depends on gravity theory. In Einstein's gravity, it is equally spaced, otherwise it is non-equidistant. This conjecture agrees with the result of Kothawala, Padmanabhan and Sarkar.
