The limit on for tachyon dark energy
Ximing Chen, Yungui Gong
We get the same degeneracy relation between and for the tachyon fields as for quintessence and phantom fields. Our results show that the dynamics of scalar fields with…
The transient acceleration from time-dependent interacting dark energy models
Xi-ming Chen, Yungui Gong, Emmanuel N. Saridakis
The transient acceleration which the current cosmic acceleration is not eternal is possible by introducing the interaction between dark matter and dark energy. If the energy transf…
Constraining the interacting dark energy models from weak gravity conjecture and recent observations
Ximing Chen, Bin Wang, Nana Pan +1
We examine the effectiveness of the weak gravity conjecture in constraining the dark energy by comparing with observations. For general dark energy models with plausible phenomenol…
The dynamical behavior of the Extended Holographic Dark Energy with Hubble Horizon
Jie Liu, Yungui Gong, Ximing Chen
The extended holographic dark energy model with the Hubble horizon as the infrared cutoff avoids the problem of the circular reasoning of the holographic dark energy model. Unfortu…
Phase-space analysis of interacting phantom cosmology
Xi-ming Chen, Yungui Gong, Emmanuel N. Saridakis
We perform a detailed phase-space analysis of various phantom cosmological models, where the dark energy sector interacts with the dark matter one. We examine whether there exist l…
Fixed points in interacting dark energy models
Xi-ming Chen, Yungui Gong
The dynamical behaviors of two interacting dark energy models are considered. In addition to the scaling attractors found in the non-interacting quintessence model with exponential…
