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…
Noncommutativity as a Possible Origin of the Ultrahigh Energy Cosmic Ray and the TeV-photon Paradoxes
Shao-Xia Chen, Zhao-Yu Yang
In this paper, we present a general modified dispersion relation derived from q-deformed noncommutative theory and apply it to the ultrahigh energy cosmic ray and the TeV-photon pa…
Thermodynamics of a deformed Bose gas
Zhe Chang, Shao-Xia Chen
By making use of the double-time Green function technique, we study thermodynamics of a deformed Bose gas, which describes well properties of density intensive photonic gas and rad…
