De Sitter时空下黑洞和宇宙视界面的热力学

The Thermodynamics of Black Hole and Cosmological Horizon in De-Sitter Spacetime

首先分别计算了Ressner-Nordstrom de Sitter时空中黑洞视界面和宇宙学视界面的表面张力,并利用表面张力得到修改的热力学第一定律,它们满足相应的斯马尔关系式。在黑洞视界和宇宙视界,热力学第一定律呈现出不同的形式。

Firstly,the surface tensions of the black hole horizon plane and the cosmological horizon plane in Reissner-Nordstrom de Sitter space-time are calculated respectively. Then,the surface tensions are used to deduce the modified first law of thermodynamics that obey the corresponding Smarr relations. It is found that the law of the black hole horizon and the cosmology horizon take on different forms.
