Specific Heat Capacities of the Quantum BTZ Black Hole in Extended Thermodynamics: A Braneworld Perspective

This paper investigates the specific heat capacities of a quantum-corrected BTZ black hole in a braneworld model, revealing novel thermodynamic features, including a critical point and regions of super-entropicity, and raising questions about the relationship between super-entropicity and thermodynamic instability in the context of modified gravity.
