具有$\mathrm{AdS}_5\times S^5$渐近性的带电超对称黑洞熵的弦修正

Stringy corrections to the entropy of electrically charged supersymmetric black holes with $\mathrm{AdS}_5\times S^5$ asymptotics

João F. Melo, Jorge E. Santos

摘要:

研究了用AdS $_5\times S^5$渐近方法对某些黑洞熵的主要$α^\prime$修正.我们发现,在超对称极限下,熵不接受$α^\prime$修正。这一结果加强了最近的计算,匹配指数的$\mathcal{N}=4$超杨米尔斯与相应的配分函数在超对称极限。在小温度区,我们发现熵修正与弱引力猜想是一致的。

英文摘要:

We study the leading $α^\prime$ corrections to the entropy of certain black holes with AdS$_5\times S^5$ asymptotics. We find that, in the supersymmetric limit, the entropy does not receive $α^\prime$ corrections. This result strengthens recent calculations that match the index of $\mathcal{N}=4$ Super-Yang-Mills with the corresponding partition function in the supersymmetric limit. In the small temperature regime, we find that the entropy corrections are concordant with the weak gravity conjecture.
