论文摘要
我们研究并讨论非线性电动力学（NED）在扩展相空间中通过黑洞充电的临界行为。负宇宙常数被视为热力压力，黑洞质量被视为化学焓。我们显示了使用Van der Waals液体系统研究的热力学和相变的类比。我们引入了与NED耦合和磁性电荷结合的新热力学量。事实证明，黑洞热力学的第一个低点和Smarr关系保持。我们已经计算了焦耳 - 汤姆森热力学系数和反转温度以及焦耳 - thomson绝热膨胀。
We study and discuss the critical behavior of charged by nonlinear electrodynamics (NED) AdS black holes in an extended phase space. The negative cosmological constant is treated as a thermodynamic pressure and the black hole mass is considered as the chemical enthalpy. We show the analogy of thermodynamics and phase transitions studied with the Van der Waals liquid-gas system. We introduce new thermodynamic quantities conjugated to the NED coupling and a magnetic charge. It was demonstrated that the first low of black hole thermodynamics and the Smarr relation hold. We have calculated the Joule--Thomson thermodynamic coefficient and inversion temperature and the Joule--Thomson adiabatic expansion is investigated.
