AI总结:

本研究针对视界分类带来的表面引力定义差异问题,在五维Gauss-Bonnet黑洞与Barrow熵构造两种场景下,分析稳态黑洞表面引力的经典定义及径向压力,探讨量子涨落对表面引力和熵的影响,深化对黑洞热力学的理解。

摘要:

由于视界存在不同的分类,我们对视界的表面引力(SG)有不同的定义。表面引力在黑洞(BH)热力学定律中具有基础性作用,在事件视界上为常数。表面引力还参与霍金辐射的发射,与其温度相关。就这一点而言,贯穿霍金辐射的量子特征直接表明,黑洞的温度与其面积直接相关,且其熵与视界面积成正比。在本工作中,我们分析了事件视界的若干方面,探究了稳态黑洞的表面引力如何通过经典方式定义,同时进行了径向压力计算。因此,通过黑洞力学定律,表面引力与热谱的真实热力学温度相关联。我们在两种不同的黑洞场景下讨论了这些主题:五维Gauss-Bonnet黑洞场景,以及近期提出的Barrow熵构造场景。我们还讨论了量子涨落如何影响这两个物理量。

英文摘要:

We have different definitions of the surface gravity (SG) of a horizon since we can say we have distinct classifications of horizons. The SG has an underlying role in the laws of black hole (BH) thermodynamics, being constant in the event horizon. The SG also acts in the emission of Hawking radiation being connected to its temperature. Concerning this last issue, the quantum features that permeate Hawking radiation provide us a direct indication that a BH has its temperature directly connected to its area and that its entropy is proportional to the horizon area. In this work we analyzed some aspects of event horizons. Analyzing how the SG can be classically defined for stationary BHs together with the radial pressure computation. So, the SG, through the laws of BH mechanics is connected to the real thermodynamical temperature of a thermal spectrum. We discussed these subjects in two different BHs scenarios, the five dimensional Gauss-Bonnet one and the recently developed Barrow entropy construction. We discussed how the quantum fluctuations affect these both quantities.
