论文摘要
使用热力学长度的概念,热力学的第一定律始终用于两个相等的Kerr-Newman黑洞的二元构型,该构型由无质量的支柱隔开。就像在两个reissner-nordström黑洞和固定的真空系统的静电系统中一样以简洁的分析形式详细说明$ \ ell $。在两个通用的Kerr-Newman黑洞的情况下,自由能的表达。
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.
