Debye entropic force and modified Newtonian dynamics
Xin Li, Zhe Chang
Verlinde has suggested that the gravity has an entropic origin, and a gravitational system could be regarded as a thermodynamical system. It is well-known that the equipartition la…
Lorentz Invariance Violation and Symmetry in Randers--Finsler Spaces
Zhe Chang, Xin Li
Lorentz Invariance violation is a common feature of new physics beyond the standard model. We show that the symmetry of Randers spaces deduces a modified dispersion relation with c…
Towards a CPT Invariant Quantum Field Theory on Elliptic de Sitter Space
Zhe. Chang, Xin. Li
Consequences of Schrödinger's antipodal identification on quantum field theory in de Sitter space are investigated. The elliptic identification provides observers wi…
Vacuum Energy Density and Cosmological Constant in dS Brane World
Zhe Chang, Shao-Xia Chen, Xin-Bing Huang +1
We discuss the vacuum energy density and the cosmological constant of dS brane world with a dilaton field. It is shown that a stable AdS brane can be constructed and gravit…
Minkowski Brane in Asymptotic dS Spacetime without Fine-tuning
Zhe Chang, Shao-Xia Chen, Xin-Bing Huang
We discuss properties of a 3-brane in an asymptotic 5-dimensional de-Sitter spacetime. It is found that a Minkowski solution can be obtained without fine-tuning. In the model, the…
Global geometric properties of AdS space and the AdS/CFT correspondence
Qi-Keng Lu, Zhe Chang, Han-Ying Guo
The Poisson kernels and relations between them for a massive scalar field in a unit ball with Hua's metric and conformal flat metric are obtained by describing the as a…
