Lovelock引力的孤立临界点

Isolated critical point from Lovelock gravity

Brian P. Dolan, Anna Kostouki, David Kubiznak, Robert B. Mann

摘要:

对任意K(=2k+1)阶具有微调Lovelock耦合的Lovelock引力,我们证明了双曲真空黑洞相图中存在一个特殊的孤立临界点,该临界点具有非标准临界指数.在吉布斯自由能中,这对应于两个燕尾出现的地方,从而在小黑洞和大黑洞之间产生两个一阶相变。我们相信,这是第一个例子的临界点与非标准的临界指数获得的几何理论的重力。

英文摘要:

For any K(=2k+1)th-order Lovelock gravity with fine-tuned Lovelock couplings, we demonstrate the existence of a special isolated critical point characterized by non-standard critical exponents in the phase diagram of hyperbolic vacuum black holes. In the Gibbs free energy this corresponds to a place wherefrom two swallowtails emerge, giving rise to two first-order phase transitions between small and large black holes. We believe that this is a first example of a critical point with non-standard critical exponents obtained in a geometric theory of gravity.
