Static Black Holes and Iyer-Wald Entropy in Gravity
I. Díaz-Saldaña, J. López-Domínguez, Wilfredo Yupanqui +2
We investigate static, spherically symmetric black hole solutions in a class of higher-curvature gravitational theories described by a Lagrangian that depends on the Ricci and Kret…
Observational constraints on entropic cosmology
Javier Chagoya, I. Díaz-Saldaña, Mario H. Amante +2
In this work, we derive a generalized modified Friedmann equation based on an entropy-area relation that incorporates established modifications, such as volumetric, linear, and log…
On the entropy of a stealth vector-tensor black hole
Javier Chagoya, I. Díaz-Saldaña, J. C. López-Domínguez +1
We apply Wald's formalism to a Lagrangian within generalised Proca gravity that admits a Schwarzschild black hole with a non-trivial vector field. The resulting entropy differs fro…
Cosmic acceleration in entropic cosmology
Javier Chagoya, I. Díaz-Saldaña, J. C. López-Domínguez +1
In this paper we study the viability of an entropic cosmological model. The effects of entropic gravity are derived from a modified entropy-area relationship with a volumetric entr…
An Effective Cosmological Constant From an Entropic Formulation of Gravity
I. Díaz-Saldaña, J. López-Domínguez, M. Sabido
We use the ideas of entropic gravity to derive the FRW cosmological model and show that for late time evolution we have an effective cosmological constant. By using the first law o…
