在球对称带电高斯-邦纳- ads黑洞背景下，在温度-热熵平面上观察到类范德华相变。利用AdS/CFT，研究了场理论对偶到球对称带电高斯-波内- AdS黑洞中重算子的全息纠缠熵、Wilson环和两点相关函数等非局域观测。在这样的重力背景下，它们都表现出固定电荷参数或高斯-邦纳参数下的类范德华相变。此外，在不同电荷值或不同高斯-邦纳参数的情况下，发现热容的等面积定律和临界指数与温度-热熵平面的相结构一致。
The Van der Waals-like phase transition is observed in temperature–thermal entropy plane in spherically symmetric charged Gauss–Bonnet–AdS black hole background. In terms of AdS/CFT, the non-local observables such as holographic entanglement entropy, Wilson loop, and two point correlation function of very heavy operators in the field theory dual to spherically symmetric charged Gauss–Bonnet–AdS black hole have been investigated. All of them exhibit the Van der Waals-like phase transition for a fixed charge parameter or Gauss–Bonnet parameter in such gravity background. Further, with choosing various values of charge or Gauss–Bonnet parameter, the equal area law and the critical exponent of the heat capacity are found to be consistent with phase structures in temperature–thermal entropy plane.
