Abstract By treating the cosmological constant as a thermodynamic pressure, we investigate the thermodynamic behaviors of Born-Infeld AdS black hole in 4D Einstein-Gauss-Bonnet (EGB) gravity. The result shows that the Van der Waals like small/large black hole (SBH/LBH) phase transition always appears for any positive parameters α and β. Moreover, we observe a new phenomenon of small/intermediate/large black hole (SBH/IBH/LBH) phase transition with one tricritical and two critical points in the available parameter region for α and β. This behavior is reminiscent of the solid/liquid/gas phase transition.

4D Einstein-Gauss-Bonnet引力中Born-Infeld AdS黑洞的三重点和相图

摘要 通过将宇宙学常数视为热力学压力,我们研究了玻恩-因菲尔德 AdS 黑洞在 4D 爱因斯坦-高斯-博内 (EGB) 引力中的热力学行为。结果表明,对于任何正参数 α 和 β,范德华像小/大黑洞 (SBH/LBH) 相变总是出现。此外,我们观察到一种新的小/中/大黑洞 (SBH/IBH/LBH) 相变现象,在 α 和 β 的可用参数区域中有一个三临界点和两个临界点。这种行为让人想起固/液/气相转变。
