Fractional-order phase transition of charged AdS black holes

Employing the tillman 750m fractional derivatives, one can construct a more elaborate classification of phase transitions compared to the original Ehrenfest classification.In this way, a thermodynamic system can even undergo a fractional-order phase transition.We use this method to restudy the charged AdS black hole and Van der Waals fluids and find that at the critical point they both click here have a 4/3-order phase transition, but not the previously recognized second-order one.
