黑洞超辐射的微观理论

Microscopic Theory of Black Hole Superradiance

Oscar J. C. Dias, Roberto Emparan, Alessandro Maccarrone

摘要:

我们研究了旋转黑洞的弦微观模型中黑洞超辐射是如何出现的。为了解开超辐射从有限温度的影响,我们考虑一个极端的,旋转的D1-D5-P黑洞,有一个能层,是不是超对称的。我们解释了微观对偶如何解释这个黑洞的超辐射能层。超辐射模频率上的0<Ω < m Ω_H界被认为是对偶CFT中自旋携带自由度的费米-狄拉克统计的结果。我们还计算了超辐射发射率从双方的对应关系,并显示他们的协议。

英文摘要:

We study how black hole superradiance appears in string microscopic models of rotating black holes. In order to disentangle superradiance from finite-temperature effects, we consider an extremal, rotating D1-D5-P black hole that has an ergosphere and is not supersymmetric. We explain how the microscopic dual accounts for the superradiant ergosphere of this black hole. The bound 0< omega < m Omega_H on superradiant mode frequencies is argued to be a consequence of Fermi-Dirac statistics for the spin-carrying degrees of freedom in the dual CFT. We also compute the superradiant emission rates from both sides of the correspondence, and show their agreement.
