两个排列Kerr-Newman黑洞的热力学

Thermodynamics of two aligned Kerr-Newman black holes

H. García-Compeán, V. S. Manko, C. J. Ramírez-Valdez

摘要:

利用热力学长度的概念,对两个被无质量支柱隔开的相等的Kerr-Newman黑洞的二元组态,一致地导出了热力学第一定律.就像前面讨论的两个Reissner-Nordström黑洞的静电系统和两个Kerr黑洞的静止真空系统一样,热力学长度$\ell$也可以用同样的简单公式$\ell=L\exp(γ_0)$来定义,$L$是支柱的坐标长度,$γ_0$是支柱上度规函数$γ$的值,这使得$\ell$可以用简明的解析形式来详细说明。给出了两个一般Kerr-Newman黑洞的自由能表达式。

英文摘要:

Using the notion of thermodynamic length, the first law of thermodynamics is consistently derived for two binary configurations of equal Kerr-Newman black holes separated by a massless strut. Like in the electrostatic systems of two Reissner-Nordström black holes and stationary vacuum systems of two Kerr black holes considered earlier, the thermodynamic length $\ell$ turns out to be defined by the same simple formula $\ell=L\exp(γ_0)$, $L$ being the coordinate length of the strut and $γ_0$ the value of the metric function $γ$ on the strut, which permits the elaboration of $\ell$ in a concise analytic form. The expression of the free energy in the case of two generic Kerr-Newman black holes is also proposed.
