Revisiting the phase transition of AdS-Maxwell–power-Yang–Mills black holes via AdS/CFT tools

In the present work we investigate the Van der Waals-like phase transition of AdS black hole solution in the Einstein–Maxwell–power-Yang–Mills gravity (EMPYM) via different approaches. After reconsidering this phase structure in the entropy-thermal plane, we recall the nonlocal observables such as holographic entanglement entropy and two point correlation function to show that the both observables exhibit a Van der Waals-like behavior as the case of the thermal entropy. By checking the Maxwell's equal area law and calculating the critical exponent for different values of charge C and nonlinearity parameter q we confirm that the first and the second order phases persist in the holographic framework. Also the validity of the Maxwell law is governed by the proximity to the critical point.
