Power-law cosmological solution derived from DGP brane with a brane tachyon field
Yongli Ping, Lixin Xu, Hongya Liu +1
By studying a tachyon field on the DGP brane model, in order to embed the 4D standard Friedmann equation with a brane tachyon field in 5D bulk, the metric of the 5D spacetime is pr…
Parametrization of Tachyon Field
Ying Shao, Yuanxing Gui
We assume that universe is dominated by non-relativistic matter and tachyon field and reconstruct the potential of tachyon field directly from the effective equation of state (EOS)…
Statefinder Parameters for Tachyon Dark Energy Model
Ying Shao, Yuanxing Gui
In this paper we study the statefinder parameters for the tachyon dark energy model. There are two kinds of stable attractor solutions in this model. The statefinder diagrams chara…
The Phase Transition of Dark Energy
Wei Wang, Yuanxing Gui, Ying Shao
Considering that the universe is filled with the nonrelativistic matter and dark energy and each component is respectively satisfied with its conservation condition in the absence…
The Complex Symmetry Gravitational Theory as a New Alternative of Dark Energy
Ying Shao, Yuan-xing Gui, Wei Wang
We propose that complex symmetry gravitational theory (CSGT) explain the accelerating expansion of universe. In this paper universe is taken as the double complex symmetric space.…
The Unified Equation of State for Dark Matter and Dark Energy
Wei Wang, Yuan-xing Gui, Suhong Zhang +2
We assume that dark matter and dark energy satisfy the unified equation of state: , with , , where the pressure of dark matter has be…
