论文摘要
我们介绍了多政体相变的黑洞热力学中的第一个例子，其中三个以上不同的黑洞相位在临界点合并。在非线性电动力学的背景下，我们明确地介绍了黑洞四倍和五重点点的示例，并演示了如何获得$ n $ tuple的关键点。我们的结果表明，黑洞可以拥有到目前为止观察到的三种类型以外的多个阶段，类似于多组分化学系统的行为。我们在Gibbs阶段规则的背景下讨论了我们结果的解释。
We present the first examples in black hole thermodynamics of multicritical phase transitions, in which more than three distinct black hole phases merge at a critical point. Working in the context of non-linear electrodynamics, we explicitly present examples of black hole quadruple and quintuple points, and demonstrate how $n$-tuple critical points can be obtained. Our results indicate that black holes can have multiple phases beyond the three types observed so far, resembling the behaviour of multicomponent chemical systems. We discuss the interpretation of our results in the context of the Gibbs Phase Rule.
