Transient Accelerating Scalar Models with Exponential Potential
Wenping Cui, Yang Zhang, Zhengwen Fu
We study a known class of scalar dark energy models in which the potential is of exponential type and the current accelerating era is transient. We find that, although a decelerati…
Observational constraints on a Yang-Mills condensate dark energy model
Z. W. Fu, Y. Zhang, M. L. Tong
Using the recently released Union2 compilation with 557 Type Ia supernovae, the shift parameter of cosmic microwave background given by the WMAP7 observations, and the baryon acous…
Crossing by a single scalar field coupling with matter and the observational constraints
Ming-Lei Tong, Yang Zhang, Zheng-Wen Fu
Motivated by Yang-Mills dark energy model, we propose a new model by introducing a logarithmic correction. we find that this model can avoid the coincidence problem naturally and g…
Constraints upon the spectral indices of relic gravitational waves by LIGO S5
Y. Zhang, M. L. Tong, Z. W. Fu
With LIGO having achieved its design sensitivity and the LIGO S5 strain data being available, constraints on the relic gravitational waves (RGWs) becomes realistic. The analytical…
