On the thermodynamics of the Hayward black hole
Martín Molina, J. R. Villanueva
In light of the growing interest in the Hayward black hole solution, a detailed study on the corresponding lapse function and its roots is presented. The lapse function is expresse…

Adiabatic evolution of Hayward black hole
Mohsen Fathi, Martín Molina, J. R. Villanueva
In this letter we use the Carathéodory's approach to thermodynamics, to construct the thermodynamic manifold of the Hayward black hole. The Pfaffian form representing the infinites…

Null paths on a toroidal topological black hole in conformalWeyl gravity
J. R. Villanueva, Francisco Tapia, Martín Molina +1
The motion of massless particles on the background of a toroidal topological black hole is analyzed in the context of conformal Weyl gravity. Null geodesics, in terms of the Jacobi…
