AdS_2量子引力的近极值克尔熵

Near Extremal Kerr Entropy from AdS_2 Quantum Gravity

Alejandra Castro, Finn Larsen

摘要:

我们利用AdS_2/CFT_1对应分析了四维近极值Kerr黑洞的渐近对称性。我们找到了一个中心电荷c_R= 12 J的维拉索罗代数,它独立于作用于简并基态的维拉索罗代数(具有相同的中心荷).计算了激发态的能量,并利用Cardy公式确定了近极值熵。我们的结果与近极值Kerr黑洞的Bekenstein-Hawking面积定律是一致的。

英文摘要:

We analyze the asymptotic symmetries of near extremal Kerr black holes in four dimensions using the AdS_2/CFT_1 correspondence. We find a Virasoro algebra with central charge c_R=12J that is independent from the Virasoro algebra (with the same central charge) that acts on the degenerate ground state. The energy of the excitations is computed as well, and we can use Cardy's formula to determine the near extremal entropy. Our result is consistent with the Bekenstein-Hawking area law for near extremal Kerr black holes.
