论文摘要
在本文中，我们扩展了由半径$ r_ {b} $的球形腔所包围的黑洞的相空间，以包括$ v \equiv4πr_{b}^{3}/3 $作为热力学体积。然后在扩展的相空间中研究了Schwarzschild和Reissner-Nordstrom（RN）黑洞的热力学行为。在恒定压力下的规范合奏中，我们发现上述热力学行为与抗DE保姆（ADS）的同类体非常相似，而宇宙学常数被解释为压力。具体而言，对于腔体中的施瓦茨柴尔德黑洞发生了一阶鹰式样相变。腔中RN黑洞的相结构与范德华流体的相似度非常相似。我们的结果可能为广告黑洞的扩展热力学提供了新的视角，类比在腔中与黑洞相比。
In this paper, we extend the phase space of black holes enclosed by a spherical cavity of radius $r_{B}$ to include $V\equiv4πr_{B}^{3}/3$ as a thermodynamic volume. The thermodynamic behavior of Schwarzschild and Reissner-Nordstrom (RN) black holes is then investigated in the extended phase space. In a canonical ensemble at constant pressure, we find that the aforementioned thermodynamic behavior is remarkably similar to that of the anti-de Sitter (AdS) counterparts with the cosmological constant being interpreted as a pressure. Specifically, a first-order Hawking-Page-like phase transition occurs for a Schwarzschild black hole in a cavity. The phase structure of a RN black hole in a cavity shows a strong resemblance to that of the van der Waals fluid. Our results may provide a new perspective for the extended thermodynamics of AdS black holes by analogy with black holes in a cavity.
