Martin Fluder, Seyed Morteza Hosseini, Christoph F. Uhlemann

摘要:

我们使用最近建立的AdS $_6$ /CFT $_5$对偶来计算IIB型磁荷AdS $_6 \times S^2 \times Σ$黑洞的微观态。近地平线的限制描述的解决方案与AdS $_2 \times Σ_{\mathfrak{g}_1} \times Σ_{\mathfrak{g}_2} \times S^2 \times Σ$几何,其中$Σ_{\mathfrak{g}_i}$是黎曼曲面的常曲率和$Σ$是一个进一步的黎曼曲面的几何是翘曲。我们的结果表明,拓扑扭曲指数的建议的对偶超共形场理论精确地再现这类黑洞的Bekenstein-Hawking熵。这进一步支持了最近提出的计算五维拓扑扭曲指数的处方,并提出了对偶。我们确认的$N^4$缩放球配分函数和扩展以前的匹配球配分函数AdS $_6$解决方案与monodromy。

英文摘要:

We use recently established AdS$_6$/CFT$_5$ dualities to count the microstates of magnetically charged AdS$_6 \times S^2 \times Σ$ black holes in Type IIB. The near-horizon limit is described by solutions with AdS$_2 \times Σ_{\mathfrak{g}_1} \times Σ_{\mathfrak{g}_2} \times S^2 \times Σ$ geometry, where $Σ_{\mathfrak{g}_i}$ are Riemann surfaces of constant curvature and $Σ$ is a further Riemann surface over which the geometry is warped. Our results show that the topologically twisted indices of the proposed dual superconformal field theories precisely reproduce the Bekenstein-Hawking entropy of this class of black holes. This provides further support for a prescription to compute five-dimensional topologically twisted indices put forth recently, and for the proposed dualities. We confirm the $N^4$ scaling found in the sphere partition functions and extend previous matches of sphere partition functions to AdS$_6$ solutions with monodromy.
