On Torsion-free Vacuum Solutions of the Model of de Sitter Gauge Theory of Gravity
Chao-Guang Huang, Yu Tian, Xiaoning Wu +1
It is shown that all vacuum solutions of Einstein field equation with a positive cosmological constant are the solutions of a model of dS gauge theory of gravity. Therefore, the mo…
Snyder's Model -- de Sitter Special Relativity Duality and de Sitter Gravity
Han-Ying Guo, Chao-Guang Huang, Yu Tian +3
Between Snyder's quantized space-time model in de Sitter space of momenta and the \dS special relativity on \dS-spacetime of radius with Beltrami coordinates, there is a one-to…
De Sitter Thermodynamics from Diamonds's Temperature
Yu Tian
The thermal time hypothesis proposed by Rovelli [1] regards the physical basis for the flow of time as thermodynamical and provides a definition of the temperature for some special…
A Note on the Generalization of the GEMS Approach
Hong-Zhi Chen, Yu Tian
This paper is a supplement of our earlier work JHEP 0410 (2004) 011[gr-qc/0409107].We map the vector potential of charged black holes into GEMS and find that its effect on the ther…
The GEMS Approach to Stationary Motions in the Spherically Symmetric Spacetimes
Hong-Zhi Chen, Yu Tian, Yi-Hong Gao +1
We generalize the work of Deser and Levin on the unified description of Hawking radiation and Unruh effect to general stationary motions in spherically symmetric black holes. We ha…
SO(1,1) dark energy model and the universe transition
Yi-Huan Wei, Yu Tian
We suggest a scalar model of dark energy with the SO(1,1) symmetry. The model may be reformulated in terms of a real scalar field and the scale factor so that the Lagrangia…
