New perspective for black hole thermodynamics in Gauss Bonnet Born Infeld massive gravity
Following an earlier study regarding Einstein Gauss Bonnet massive black holes in the presence of a Born Infeld nonlinear electromagnetic field (Hendi, arXiv:1510.00108, 2016) we study thermodynamical structure and critical behavior of these black holes through various methods in this paper. Geometrical thermodynamics is employed to give a picture regarding the phase transition of these black holes. Next, a new method is used to derive critical pressure and radius of the horizon of these black holes. In addition, Maxwell equal area law is employed to study the Van der Waals like behavior of these black holes. Moreover, the critical exponents are calculated and by using Ehrenfest equations, the type of phase transition is determined.
