One Gravity, Many G's: Generalized Horizon Entropy and Gravitational Susceptibility
Yen Chin Ong
Effective and thermodynamic derivations of gravity theory in the context of generalized entropy can give rise to multiple, and potentially varying, gravitational couplings, raising…
How Much Geometry Does Horizon Entropy Determine? A Discourse on Entropy, Gravity, and Observable Quantities
Yen Chin Ong
Building on Jacobson's thermodynamics derivation of Einstein field equations, the "generalized entropy and varying-G" (GEVAG) framework was proposed to consistently incorporate gen…
Cosmology with Logarithmic Corrected Horizon Entropy According to the Generalized Entropy and Variable-G Correspondence
Chen-Hao Wu, Yen Chin Ong
According to the GEVAG (Generalized Entropy Varying-G) framework, any modification to the Bekenstein-Hawking area law would also lead to a varying- gravity theory in which the e…
Kiselev Black Holes in Anti-de Sitter Spacetime Are Not Viable
Jiayi Xia, Yen Chin Ong
While the Kiselev black hole solution does not describe a perfect fluid quintessence, it is possible that dark energy fluid is not isotropic, and so one may hope that the solution…
Insights in cosmology: the relevance of the connection
Ismael Ayuso, Mariam Bouhmadi-López, Che-Yu Chen +3
We explore the role of the affine connection in gravity, a modified theory where gravity is governed by non-metricity within the symmetric teleparallel framework. Although t…
Do Black Holes With Generalized Entropy Violate Bekenstein Bound?
Hengxin Lu, Yen Chin Ong
In general yes, but also not quite. It is known that if the Bekenstein-Hawking entropy is replaced by some kind of generalized entropy, then the Bekenstein bound may be grossly vio…
