摘要:

本文在扩展相空间中研究了四维Einstein-Gauss-Bonnet引力场中Hayward-AdS黑洞的$P-V$临界性和Joule-Thomson展开。我们发现,对于任意正的参数$α$和$g$,黑洞总是表现出类似于范德华系统的相变.研究了$α$和$g$对反转曲线的依赖关系,并在$T-P$平面上绘制了反转曲线和等焓曲线,从而确定了冷却区和加热区。

英文摘要:

In this paper, the $P-V$ criticality and Joule-Thomson Expansion of Hayward-AdS black holes in 4D Einstein-Gauss-Bonnet gravity are studied in the extended phase space. We find the black hole always exhibits a phase transition similar to that of the Van der Waals system for any arbitrary positive parameters $α$ and $g$. We also study the dependence of $α$ and $g$ on the inversion curves and plot the inversion and isenthalpic curves in the $T-P$ plane, which can determine the cooling-heating regions.
