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…
Mechanics and Newton-Cartan-Like Gravity on the Newton-Hooke Space-time
Yu Tian, Han-Ying Guo, Chao-Guang Huang +2
We focus on the dynamical aspects of Newton-Hooke space-time mainly from the viewpoint of geometric contraction of the de Sitter spacetime. We first discuss the Newto…
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…
On de Sitter Invariant Special Relativity and Cosmological Constant as Origin of Inertia
Han-Ying Guo, Chao-Guang Huang, Yu Tian +2
Weakening the Euclidean assumption in special relativity and the coordinate-independence hypothesis in general relativity for the de Sitter space, we propose a de Sitter invariant…
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…
Topological Charge of ADHM Instanton on R^2_{NC}*R^2
Yu Tian
We have calculated the topological charge of U(N) instantons on non-degenerate noncommutative space time to be exactly the instanton number k in a previous paper [Mod.Phys.Lett. A1…
