事件视界上的引力压力和遥平行框架下的热力学

Gravitational pressure on event horizons and thermodynamics in the teleparallel framework

J. W. Maluf, S. C. Ulhoa, J. F. da Rocha-Neto

摘要:

引力压的概念自然是在广义相对论的远程平行等价物的上下文中定义的。结合引力能的定义,我们在遥平行框架下研究了旋转黑洞的热力学。我们得到了Kerr黑洞外事件视界上的引力压值,并给出了Kerr黑洞的热力学关系式$TdS =dE + pdV$的表达式,其中的变化是指Penrose过程.我们只采用在遥平行引力中产生的引力能和引力压的概念,而不考虑事件视界的面积或面积的变化。然而,我们的结果是定性类似的标准表达的文献。

英文摘要:

The concept of gravitational pressure is naturally defined in the context of the teleparallel equivalent of general relativity. Together with the definition of gravitational energy, we investigate the thermodynamics of rotating black holes in the teleparallel framework. We obtain the value of the gravitational pressure over the external event horizon of the Kerr black hole, and write an expression for the thermodynamic relation $TdS =dE + pdV$, where the variations refer to the Penrose process for the Kerr black hole. We employ only the notions of gravitational energy and pressure that arise in teleparallel gravity, and do not make any consideration of the area or the variation of the area of the event horizon. However, our results are qualitatively similar to the standard expression of the literature.
