摘要:

黑洞力学第二定律和WCCC在黑洞的焓作为质量及其相关热力学性质的背景下的验证还没有通过大量的文献在最近的过去测试。这些研究具有重要的物理意义,因为它们为我们提供了大量关于AdS黑洞系统热力学和动力学的信息。我们利用先前有限的研究结果来研究$D$维渐近AdS带电黑洞的WCCC,该黑洞的特征为质量($M$)、电荷($Q$)和AdS半径($l$),在标量带电粒子$q$的吸收下.我们通过分析被黑洞吸收的带电粒子的能量-动量条件来研究WCCC。我们证明了无论初始黑洞配置是极值或非极值,通过改变其电荷,AdS半径,以及它们的变化,该猜想得到了很好的验证。我们表明,第一定律和WCCC是有效的所有时空维度($D$)独立的参数的选择表征的黑洞。但要验证第二定律在极端和非极端的配置之一,必须非常谨慎,因为它得到强烈影响的选择值的黑洞参数及其变化.在扩展相空间的背景下,考虑巨正则势允许我们获得所缺少的信息的宇宙学常数的变化,必要的构建扩展相空间,即黑洞压力的概念,这是在以前的文献中没有到目前为止。

英文摘要:

The verification of the second law of black hole mechanics and the WCCC in the context of enthalpy as mass of the black hole and its related thermodynamic properties has not been tested through a vast number of literature in the recent past. Such studies are of great physical importance as they provide us with a large number of information regarding the thermodynamics and the dynamics of AdS black hole systems. We invest the prior limited surveys of such analysis to investigate the WCCC for the $D$- dimensional asymptotically AdS-charged black holes characterized by its mass ($M$), electric charge ($Q$), and AdS radius ($l$) under the absorption of scalar particles of charge $q$. We examine the WCCC by analyzing the energy-momentum condition of the electrically charged particles as absorbed by the black holes. We prove that the conjecture is well verified irrespective of whether the initial black hole configurations are extremal or non-extremal by changing its charge, the AdS radius, and their variations. We show that the first law and the WCCC are valid for all spacetime dimensions ($D$) independent of the choice of the parameters characterizing the black holes. But to verify the second law in the extremal and non-extremal configurations one has to be very cautious as it gets strongly affected by the choices of the values of the black hole parameters and their variations... In the context of the extended phase space, taking the grand canonical potential into account allow us to obtain the missing information about the variation of the cosmological constant necessary to construct the extended phase space, namely the notion of the black hole pressure, and which is absent in the previous literature so far.
