Quantum Yang-Mills Condensate Dark Energy Models
W. Zhao, Y. Zhang, M. L. Tong
We review the quantum Yang-Mills condensate (YMC) dark energy models. As the effective Yang-Mills Lagrangian is completely determined by the quantum field theory, there is no adjus…
Relic Gravitational Waves with A Running Spectral Index and Its Constraints at High Frequencies
Ming-Lei Tong, Yang Zhang
We study the impact of a running index on the spectrum of relic gravitational waves (RGWs) over the whole range of frequency Hz and reveal its implic…
Cosmic age, Statefinder and diagnostics in the decaying vacuum cosmology
Ming-Lei Tong, Yang Zhang
As an extension of CDM, the decaying vacuum model (DV) describes the dark energy as a varying vacuum whose energy density decays linearly with the Hubble parameter in the late-t…
New method to constrain the relativistic free-streaming gas in the Universe
Wen Zhao, Yang Zhang, Tianyang Xia
We discuss a method to constrain the fraction density of the relativistic gas in the radiation dominant stage, by their impacts on a relic gravitational waves and the cosmic mi…
