摘要
Using numerical and perturbative methods, we construct the first examples of black hole solutions in Einsteinian cubic gravity and study their thermodynamics. Focusing first on four-dimensional solutions, we show that these black holes have a novel equation of state in which the pressure is a quadratic function of the temperature. Despite this, they undergo a first order phase transition with associated van der Waals behavior. We then construct perturbative solutions for general D >= 5 and study the properties of these solutions for D = 5 and D = 6 in particular. We note that for D > 4 the solutions are described by two independent metric functions. We find novel examples of super-entropic behavior over a large portion of the parameter space. We analyze the specific heat, determining that the black holes are thermodynamically stable over large regions of parameter space.
