Effects of global monopole on critical behaviors and microstructure of charged AdS black holes (2102.02083v1)

Abstract: As an intriguing topological defect, global monopole's influence on behaviors of black holes has always been anticipated but still remains less clear. Analyzing the thermodynamics of charged AdS black hole incorporating a global monopole manifests that the black hole undergoes a first-order phase transition at critical point, and of special interest, the critical behaviors qualitatively resemble a Van der Waals liquid-gas system. This paper concentrates on further investigating the charged AdS black hole with a global monopole, aiming at clarifying the significant effects of the global monopole on criticality and microstructure of charged AdS black holes. An interesting dependence on the internal global monopole can be witnessed intuitively by employing contrastive illustrations.
