Constraints on the generalized Chaplygin gas model including gamma-ray bursts via a Markov Chain Monte Carlo approach
Nan Liang, Lixin Xu, Zong-Hong Zhu
We investigate observational constraints on the generalized Chaplygin gas (GCG) model including the gamma-ray bursts (GRBs) at high redshift obtained directly from the Union2 type…
Constraints on modified Chaplygin gas from recent observations and a comparison of its status with other models
Jianbo Lu, Lixin Xu, Jiechao Li +3
In this Letter, a modified Chaplygin gas (MCG) model of unifying dark energy and dark matter with the exotic equation of state is constrained…
Cosmological constraints on generalized Chaplygin gas model: Markov Chain Monte Carlo approach
Lixin Xu, Jianbo Lu
We use the Markov Chain Monte Carlo method to investigate a global constraints on the generalized Chaplygin gas (GCG) model as the unification of dark matter and dark energy from t…
The Integrated Sachs-Wolfe Effect in Time Varying Vacuum Model
Yuting Wang, Yuan-Xing Gui, Lixin Xu +1
The integrated Sachs-Wolfe (ISW) effect is an important implication for dark energy. In this paper, we have calculated the power spectrum of the ISW effect in the time varying vacu…
Born-Oppenheimer approximation for open quantum systems within the quantum trajectory approach
X. L. Huang, S. L. Wu, L. C. Wang +1
Based on the quantum trajectory approach, we extend the Born-Oppenheimer (BO) approximation from closed quantum system to open quantum system, where the open quantum system is desc…
The influence of quintessence on the motion of a binary system in cosmology
Fei Yu, Molin Liu, Yuanxing Gui
We employ the metric of Schwarzschild space surrounded by quintessential matter to study the trajectories of test masses on the motion of a binary system. The results, which are ob…
