Cosmological Constraints on Non-flat Exponential Gravity
Chao-Qiang Geng, Yan-Ting Hsu, Jhih-Rong Lu
We explore the viable gravity models in FLRW backgrounds with a free spatial curvature parameter . In our numerical calculation, we concentrate on the exponential $f(…
A Dark Energy model from Generalized Proca Theory
Chao-Qiang Geng, Yan-Ting Hsu, Jhih-Rong Lu +1
We consider a specific dark energy model, which only includes the Lagrangian up to the cubic order in terms of the vector field self-interactions in the generalized Proca theory. W…
Modified Cosmology Models from Thermodynamical Approach
Chao-Qiang Geng, Yan-Ting Hsu, Jhih-Rong Lu +1
We apply the first law of thermodynamics to the apparent horizon of the universe with the power-law corrected and non-extensive Tsallis entropies rather than the Bekenstein-Hawking…
Thermodynamics of Gravity with Disformal Transformation
Chao-Qiang Geng, Wei-Cheng Hsu, Jhih-Rong Lu +1
We study thermodynamics in gravity with the disformal transformation. The transformation applied to the matter Lagrangian has the form of $\g_{\m\n} = A(ϕ,X)g_{\m\n} + B(ϕ,X…
