关于熵积和对偶CFTs的更多信息

More on the Entropy Product and Dual CFTs

Hanif Golchin

摘要:

本文检验了某些黑洞和黑环解的熵积的普适性。应用渐近对称群(ASG)分析,我们还找到了这些解决方案的对偶CFTs的中心荷。已经观察到\cite{Chen:2013rb},如果解的熵积是普适的,则可以从熵积中读取对偶CFTs的中心荷为$c_i \sim \frac{\partial}{\partial N_i}(S_+S_-)$,其中$N_i$是解的守恒电荷,如角动量或电荷。在这项工作中,我们考虑一些其他家庭的解决方案,我们检查,同样的行为是有效的。此外,在含有圆锥奇点的解的情况下,我们找到了中心荷使用ASG分析。我们表明,中心电荷接收的贡献,从锥形特性$κ$的解决方案,但它仍然是可能的读取中心荷从熵积。

英文摘要:

In this paper, we check the universality of the entropy product for some black hole and black ring solutions. Applying the asymptotic symmetry group (ASG) analysis, we also find the central charges of the dual CFTs for these solutions. It has been observed \cite{Chen:2013rb} that if the entropy product for a solution is universal, it is possible to read the central charges of the dual CFTs from the entropy product as $c_i \sim \frac{\partial}{\partial N_i}(S_+S_-)$, where $N_i$ is a conserved charge of the solution like angular momentum or electric charge. In this work, we consider some other families of solutions and we check that the same behavior is valid for them. Moreover, in the case of solutions containing the conical singularity, we find the central charges using the ASG analysis. We show that the central charges receive a contribution from the conical characteristic $κ$ of the solution, however it is still possible to read the central charges from the entropy product.
