Abstract

In this paper, we provide a thermodynamical study of charged accelerating AdS black holes in the [Formula: see text]-metric. In this connection, we first determine the mass of the given black hole and study their dependence on horizon radius and acceleration. Furthermore, following black hole mechanics, we also derive various quantities like Hawking temperature, entropy, pressure, volume, internal energy, Gibbs energy and Helmholtz energy. With the help of a graph, we study the effect of acceleration on these thermal quantities. Here, we observe that the impact of acceleration becomes more significant on the large horizons. To discuss stability and phase transition, we calculate specific heat. The graphical analysis suggests multiple phase transitions occur for the charged accelerating black hole in AdS spacetime. The system changes state at the critical point, where phase transition occurs. For the small black holes, the critical point at which the phase transition occurs is independent of the acceleration parameter. However, the critical horizon radius for large black holes depends on the acceleration parameter. For fast-accelerating black holes, a phase transition occurs at a small horizon radius to that of slowly accelerating black holes.

带电加速 AdS 黑洞的热力学
在本文中,我们用[公式:见正文]度量法对带电加速 AdS 黑洞进行了热力学研究。为此,我们首先确定了给定黑洞的质量,并研究了它们与视界半径和加速度的关系。此外,根据黑洞力学,我们还得出了霍金温度、熵、压力、体积、内能、吉布斯能和赫尔姆霍兹能等各种量。借助图表,我们研究了加速度对这些热量的影响。在这里,我们观察到加速度对大视界的影响变得更加显著。为了讨论稳定性和相变,我们计算了比热。图形分析表明,AdS 时空中的带电加速黑洞会发生多重相变。系统在临界点发生状态变化,相变发生在临界点。对于小黑洞,发生相变的临界点与加速度参数无关。然而,大黑洞的临界视界半径取决于加速度参数。对于快速加速的黑洞,相变发生在较小的视界半径处,而对于缓慢加速的黑洞,相变发生在较小的视界半径处。
