BMPV黑洞的量子熵与拓扑M理论猜想

Quantum entropy of BMPV black holes and the topological M-theory conjecture

Rajesh Kumar Gupta, Sameer Murthy, Manya Sahni

摘要:

本文给出了在$CY_3$上紧化的M-理论中超对称五维自旋黑洞的量子熵公式,BMPV黑洞。我们在离壳五维$N=2$超引力耦合到$I = 1,\dots,N_V + 1$离壳矢量多重态的框架下使用超对称局域化。该理论在二阶导数水平上由对称张量$\mathcal{C}_{IJK}$(卡-丘的交叉数)控制,在四阶导数水平上由规范-引力Chern-Simons耦合$c_I$(卡-丘的第二类Chern)控制。量子熵是一个$N_V + 2$维积分参数化的一个真正的参数$φ^I$为每个矢量多重和一个额外的参数$φ^0$的重力多重。被积函数由一个完全由$\mathcal{C}_{IJK}$和$c_{I}$控制的作用和一个单圈行列式组成。与熵的壳层对数修正、模空间非常特殊的几何对称性以及解析性假设的一致性,将单圈行列式限制为与尺度无关的函数$f(φ^0)$。对于$f=1$,我们的结果与Dijkgraaf,Gukov,Nietzke,和Vafa关于静态黑洞的拓扑M理论猜想在二阶导数水平上完全一致,并提供了一个自然的推广到高阶导数修正.对于旋转的BMPV黑洞,我们的结果与DGNV猜想在第一量子修正水平上不同。

英文摘要:

We present a formula for the quantum entropy of supersymmetric five-dimensional spinning black holes in M-theory compactified on $CY_3$, i.e., BMPV black holes. We use supersymmetric localization in the framework of off-shell five dimensional $N=2$ supergravity coupled to $I = 1,\dots,N_V + 1$ off-shell vector multiplets. The theory is governed at two-derivative level by the symmetric tensor $\mathcal{C}_{IJK}$ (the intersection numbers of the Calabi-Yau) and at four-derivative level by the gauge-gravitational Chern-Simons coupling $c_I$ (the second Chern class of the Calabi-Yau). The quantum entropy is an $N_V + 2$-dimensional integral parameterised by one real parameter $φ^I$ for each vector multiplet and an additional parameter $φ^0$ for the gravity multiplet. The integrand consists of an action governed completely by $\mathcal{C}_{IJK}$ and $c_{I}$, and a one-loop determinant. Consistency with the on-shell logarithmic corrections to the entropy, the symmetries of the very special geometry of the moduli space, and an assumption of analyticity constrains the one-loop determinant up to a scale-independent function $f(φ^0)$. For $f=1$ our result agrees completely with the topological M-theory conjecture of Dijkgraaf, Gukov, Nietzke, and Vafa for static black holes at two derivative level, and provides a natural extension to higher derivative corrections. For rotating BMPV black holes, our result differs from the DGNV conjecture at the level of the first quantum corrections.
