带电黑洞的准正规模熵/面积谱

Entropy/Area spectra of the charged black hole from quasinormal modes

Shao-Wen Wei, Yu-Xiao Liu, Ke Yang, Yuan Zhong

摘要:

随着Maggiore提出的准正规模的新物理解释,黑洞的量子面积谱最近得到了研究。采用改进的Hod处理,结果表明,在Einstein引力作用下,黑洞的面积谱是等间距的,且其间距具有统一的形式$\triangle A=8π\hbar$.另一方面,根据Kunstatter的方法,研究表明不带电荷的非旋转黑洞的面积谱是等距的。对于旋转(或带电)的黑洞,当黑洞远离极端情况时,它也是等距的,并且与角动量$J$(或电荷$q$)无关。本文主要研究了由低能弦论中的有效作用量导出的带弦荷Garfinkle-Horowitz-Strominger黑洞的面积谱。我们发现这两种方法给出了相同的结果,即面积谱是等间距的,并且不依赖于电荷$q$。我们的研究为理解弦黑洞的面积谱和熵谱提供了新的思路。

英文摘要:

With the new physical interpretation of quasinormal modes proposed by Maggiore, the quantum area spectra of black holes have been investigated recently. Adopting the modified Hod's treatment, results show that the area spectra for black holes are equally spaced and the spacings are in a unified form, $\triangle A=8π\hbar$, in Einstein gravity. On the other hand, following Kunstatter's method, the studies show that the area spectrum for a nonrotating black hole with no charge is equidistant. And for a rotating (or charged) black hole, it is also equidistant and independent of the angular momentum $J$ (or charge $q$) when the black hole is far from the extremal case. In this paper, we mainly deal with the area spectrum of the stringy charged Garfinkle-Horowitz-Strominger black hole, originating from effective action that emerges in the low-energy string theory. We find that both methods give the same results-that the area spectrum is equally spaced and does not depend on the charge $q$. Our study may provide new insights into understanding the area spectrum and entropy spectrum for stringy black holes.
