Investigating Graviton Mass Effects on Black Hole Lensing in dRGT Massive Gravity
Haximjan Abdusattar, Yu-Xuan Han, Abdujappar Rusul +1
In this paper, we delve into the gravitational lensing and photon trajectories in the vicinity of non-asymptotically flat black hole spacetimes within the framework of dRGT massive…
U(1) Gauge Potentials on de Sitter Spacetime
Bin Zhou, Shi-Bei Kong, Peng Zhao
The smooth 1-form Verma module of is acquired, which can be regarded as the U(1) gauge potential on de Sitter spacetime. It is shown that electromagnetic field…
Thermodynamics of the arbitrary dimensional FRW universe: Joule-Thomson expansion
Haximjan Abdusattar, Shi-Bei Kong, Minawar Omar +1
In this paper, we investigate the thermodynamics especially the Joule-Thomson expansion of the -dimensional FRW (Friedmann-Robertson-Walker) universe with a perfect fluid. We de…
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…
