摘要
近年来,带有整体磁单极的黑洞引起了人们广泛的关注。同时,人们对带有整体磁单极的黑洞的相结构也有了深入的研究。其中,两点关联函数就是研究黑洞相变结构的有利的工具之一。在本文中,不仅利用黑洞熵,还利用了两点关联函数来探讨带有整体磁单极电荷的黑洞的相变行为。而且在对应的平面内可以观察到和普通热力学液气流体完全相类似的范德瓦尔斯相变。在T-δL平面中也考虑了磁单极参数对黑洞相变行为的影响,在对应的平面中显示的结果仍然呈现与普通热力学液—气流体相类似的范德瓦尔斯相变。研究结果表明,在全息框架下,带有磁单极电荷的AdS时空中黑洞展示出与黑洞热力学熵相类似的范德瓦尔斯相变。
In recent years,black holes with global monopole have attracted widespread attention.At the same time,the phase structure of black holes with global monopole have been researched deeply.The two-point correlation function is one of the useful tools for studying the phase structure of black holes.In this paper,not only the black hole entropy but also the two-point correlation function is used to discuss the phase transition behavior of a black hole with global monopole charge.And in the corresponding plane,the Van der Waals phase transition which is completely similar to ordinary thermodynamic liquid-gas fluid can be observed.In the T-δL plane,the influence of the monopole parameter on the phase transition behavior of the black hole is also considered,and the results displayed in the corresponding plane still present the Van der Waals-like phase transition.The research results show that in the framework of holography,the AdS spacetime black hole with monopole charge exhibits a Van der Waals phase transition similar to the thermodynamic entropy of the black hole.
