Among many open questions in theoretical physics, consistent quantum gravity theory is still a major issue to be solved. Recent major works in phase transitions of black holes (BH) can be helpful for quantum interpretation of classical gravity. We study the new effective method to discuss the thermodynamic phase transitions onto well renowned regular BHs. Ordinary approaches of phase transitions depend upon equation of state and it is impossible to obtain all critical points with ordinary approaches. This study is derived from the slope of temperature versus entropy and it provides the possibility of finding all the critical points analytically. This technique provides pressure, which is different from standard relation of pressure and independent of other thermodynamical relations. We discuss some issues in ordinary methods and provide an easy approach to investigate the critical behavior of thermodynamical quantities. We find out the phase transitions points and horizon radii of non-physical range for BHs. We also use the new thermodynamical relations to briefly study well-known Joule–Thomson (JT) effect on regular BH.

新相变方法对特定黑洞的影响

在理论物理学的许多悬而未决的问题中,一致的量子引力理论仍然是一个有待解决的主要问题。最近在黑洞相变 (BH) 方面的主要工作有助于对经典引力的量子解释。我们研究了一种新的有效方法来讨论热力学相变到著名的规则 BH。相变的普通方法依赖于状态方程,普通方法不可能获得所有临界点。这项研究源自温度与熵的斜率,它提供了通过分析找到所有临界点的可能性。该技术提供压力,它不同于标准的压力关系,独立于其他热力学关系。我们讨论了普通方法中的一些问题,并提供了一种简单的方法来研究热力学量的临界行为。我们找出了 BH 的非物理范围的相变点和地平线半径。我们还使用新的热力学关系来简要研究众所周知的焦耳 - 汤姆逊(JT)对常规 BH 的影响。
