Agegraphic dark energy from entropy of the anti-de Sitter black hole
Qihong Huang, Yang Liu, He Huang
In this paper, we analyze the agegraphic dark energy from the entropy of the anti-de Sitter black hole using the age of the universe as the IR cutoff. We constrain its parameter wi…

Energy conditions for regular black holes in EFT of gravity
Ziyue Zhu, Alexey S. Koshelev, Yang Liu +1
As Einstein's gravity is a non-renormalizable theory, it can be a good description of physics only at the scales of energy or spacetime curvature below the Planck mass. Moreover, i…

Misner-Sharp Energy and P-V Criticality in Quasi-Topological Cosmology
Yue Chu, Shi-Bei Kong, Yang Liu +2
We presented a sound foundation of thermodynamics for a Friedmann-Robertson-Walker (FRW) universe from the first principle in ground-breaking work [Hu et al., JHEP12 (2022) 168]. B…
