Thermodynamic Geometry and Phase Transitions of Dyonic Charged AdS Black Holes

摘要: We investigate phase transitions and critical phenomena of four dimensional dyonic charged AdS black holes in the framework thermodynamic geometry. In a mixed canonical–grand canonical ensemble with fixed electric charge varying magnetic these exhibit liquid–gas like first order transition culminating second point similar to van der Waals gas. show that scalar curvature R for follow our proposed geometrical characterization R-crossing Method exhibits divergence at point. The pattern crossing exactly corresponds those gas described by us an earlier work.
