利用两点相关函数和全息纠缠熵等非局域观测值，研究了玻恩-因菲尔德-反德西特黑洞的相结构。当Born-Infeld参数为黑洞的电荷时，发现其相结构与范德华相变相似，即黑洞在达到稳定相之前经历了一级相变和二级相变。而在这种情况下，除了范德华相变之外，还出现了一个新的相分支。对于一阶相变，验证了等面积定律，对于二阶相变，得到了热容的临界指数。所有这些结果都与在熵温平面上观察到的结果一致。
With the non-local observables such as two point correlation function and holographic entanglement entropy, we probe the phase structure of the Born–Infeld–anti-de Sitter black holes. For the case, wherebis the Born–Infeld parameter andQis the charge of the black hole, the phase structure is found to be similar to that of the Van der Waals phase transition, namely the black hole undergoes a first order phase transition and a second order phase transition before it reaches a stable phase. While for the case, a new phase branch emerges besides the Van der Waals phase transition. For the first order phase transition, the equal area law is checked, and for the second order phase transition, the critical exponent of the heat capacity is obtained. All these results are found to be the same as that observed in the entropy–temperature plane.
