Dynamics of phantom model with O(N) symmetry in loop quantum cosmology
Zu-Yao Sun, Chun-Xiao Yue, You-Gen Shen +1
Many astrophysical data show that the expansion of our universe is accelerating. In this paper, we study the model of phantom with O(N) symmetry in background of loop quantum cosmo…
Statefinder diagnostic in a torsion cosmology
Xin-zhou Li, Chang-bo Sun, Ping Xi
We apply the statefinder diagnostic to the torsion cosmology, in which an accounting for the accelerated universe is considered in term of a Riemann-Cartan geometry: dynamic scalar…
Torsion cosmological dynamics
Xin-zhou Li, Chang-bo Sun, Ping Xi
In this paper, the dynamical attractor and heteroclinic orbit have been employed to make the late-time behaviors of the model insensitive to the initial condition and thus alleviat…
Viscous Cardassian universe
Chang-Bo Sun, Jia-Ling Wang, Xin-Zhou Li
The viscous Cardassian cosmology is discussed, assuming that there is a bulk viscosity in the cosmic fluid. The dynamical analysis indicates that there exists a singular curve in t…
Exponential Cardassian Universe
Dao-jun Liu, Chang-bo Sun, Xin-zhou Li
The expectation of explaining cosmological observations without requiring new energy sources is forsooth worthy of investigation. In this letter, a new kind of Cardassian models, c…
Heteroclinic orbit and tracking attractor in cosmological model with a double exponential potential
Xin-zhou Li, Yi-bin Zhao, Chang-bo Sun
In this paper, the dynamical heteroclinic orbit and attractor have been employed to make the late-time behaviors of the model insensitive to the initial condition and thus alleviat…
