Thermodynamics, Phase Transitions, and Geodesic Structure of F(R)-Phantom Banados-Teitelboim-Zanelli (BTZ) Black Holes

Behzad Eslam Panah, Bilel Hamil, Manuel E. Rodrigues

Claims

C1strongest claim

Our results demonstrate adherence to both Ehrenfest relations, thereby confirming the occurrence of a second-order phase transition within the black hole system concurrent with the critical point. The analysis demonstrates that stable timelike circular orbits exist only in the phantom regime for negative curvature backgrounds, while the phantom configuration also allows for stable circular photon orbits.

C2weakest assumption

The specific choice of F(R) function and the power-Maxwell nonlinear electrodynamics with phantom sign flip produce physically consistent solutions that satisfy the first law and Ehrenfest equations without unaccounted instabilities or violations of energy conditions.

C3one line summary

F(R)-phantom BTZ black holes satisfy the first law, undergo second-order phase transitions confirmed by Ehrenfest relations, and support stable circular orbits for massive and massless particles only in the phantom regime with negative curvature.
