Unifying topological, geometric, and complex classifications of black hole thermodynamics
Shi-Hao Zhang, Shao-Wen Wei, Jing-Fei Zhang +1
Black hole thermodynamics has recently witnessed three distinct classification schemes: based on local geometric properties of the temperature function, global topological invarian…
Universal geometric framework for black hole phase transitions: from multivaluedness to classification
Shi-Hao Zhang, Zi-Yuan Li, Jing-Fei Zhang +1
Recent studies have revealed synchronized multivalued behavior in thermodynamic, dynamical, and geometric quantities during the black hole first-order phase transition, which enabl…
Geometric unification of timelike orbital chaos and phase transitions in black holes
Shi-Hao Zhang, Zi-Yuan Li, Jing-Fei Zhang +1
The deep connection between black hole thermodynamics and spacetime geometry remains a central focus of general relativity. While recent studies have revealed a precise corresponde…
Gaussian curvature and Lyapunov exponent as probes of black hole phase transitions
Shi-Hao Zhang, Zi-Qiang Zhao, Zi-Yuan Li +2
First-order phase transitions of black holes have been extensively studied within thermodynamic frameworks, yet the corresponding evolution of spacetime geometric properties remain…
