从爱因斯坦物态方程看视界热力学

Horizon Thermodynamics from Einstein's Equation of State

Devin Hansen, David Kubiznak, Robert Mann

摘要:

通过将爱因斯坦方程看作状态方程,我们证明了在视界热力学中可以导出一个完整的上齐次视界第一定律。在这种方法中,熵和自由能都是导出的概念,而标准(退化)视界第一定律是由勒让德投影从更一般的一个,我们得到恢复。这些结果很容易推广到更高曲率的引力,并建立了一种方法,如何制定一致的黑洞热力学没有守恒电荷。

英文摘要:

By regarding the Einstein equations as equation(s) of state, we demonstrate that a full cohomogeneity horizon first law can be derived in horizon thermodynamics. In this approach both the entropy and the free energy are derived concepts, while the standard (degenerate) horizon first law is recovered by a Legendre projection from the more general one we derive. These results readily generalize to higher curvature gravities and establish a way of how to formulate consistent black hole thermodynamics without conserved charges.
