A Coarse-Grained Field Theory for Density Fluctuations and Correlation Functions of Galactic Objects
Yang Zhang
We present a coarse-grained field theory of density fluctuations for a Newtonian self-gravitating many-body system and apply it to a homogeneous Universe with small density fluctua…
Quintom models with an equation of state crossing -1
Wen Zhao, Yang Zhang
In this paper, we investigate a kind of special quintom model, which is made of a quintessence field and a phantom field , and the potential function has the form of $V(…
Relic gravitational waves and their detection
Wen Zhao, Yang Zhang
As the strong evidence for inflation, the relic gravitational waves (RGW) have been extensively studied. Although, it has not been detected, yet some constraints have been achieved…
Coincidence Problem in YM Field Dark Energy Model
Wen Zhao, Yang Zhang
The coincidence problem is studied in the effective Yang-Mills condensate dark energy model. As the effective YM Lagrangian is completely determined by quantum field theory, there…
An exact analytic spectrum of relic gravitational waves in an accelerating universe
Yang Zhang, XinZhong Er, TianYang Xia +2
An exact analytic calculation is presented for the spectrum of relic gravitational waves in the scenario of accelerating Universe . The spectrum formula contains expli…
