高斯-博内黑洞中心荷的临界性

Criticality of central charges for Gauss-Bonnet black holes

Hong-Ming Cui, Zhong-Ying Fan

AI总结:

本研究采用扩展相空间形式体系,探究高斯-博内黑洞对偶全息理论的A、C中心荷临界性,发现普适临界耦合与中心荷普适比,给出边界自由度视角的临界行为新诠释,并揭示转变温度的因果性上限。

摘要:

我们采用扩展相空间形式体系,研究与Gauss-Bonnet(高斯-博内)黑洞对偶的全息理论的A-荷与C-荷的临界现象。我们发现了一个普适的临界高斯-博内耦合,使得临界点处两个中心荷之间存在普适比值。这为从边界自由度角度解释高斯-博内黑洞的临界行为提供了新的诠释,尽管这些解是电中性的。另一个新特征是,对于任一中心荷,转变温度均高于临界点,但受边界理论因果性的上限约束。

英文摘要:

Employing extended phase space formalism, we study critical phenomenon of A-charge and C-charge for holographic theories dual to Gauss-Bonnet black holes. We find a universal critical Gauss-Bonnet coupling, giving rise to a universal ratio between the two central charges at the critical point. This leads to a new intepretation for critical behavior of Gauss-Bonnet black holes in terms of the boundary degrees of freedoms, although the solutions are electrically neutral. Another novel feature is for either of the central charges, the transition temperature is beyond the critical point but is upper bounded by causality of the boundary theories.
