Journal ArticleDOI
Holographic dark energy model from Ricci scalar curvature
TL;DR: In this article, the authors proposed to replace the future event horizon area with the inverse of the Ricci scalar curvature, which is phenomenologically viable and naturally solves the coincidence problem of dark energy.
Journal ArticleDOI
Does the mass of a black hole decrease due to the accretion of phantom energy
TL;DR: In this article, the authors used exact solutions describing black holes in a background Friedmann-Robertson-Walker universe, and found that the physical black hole mass may instead increase due to the accretion of phantom energy.
Journal ArticleDOI
Dilaton black holes in the de Sitter or anti-de Sitter universe
Changjun Gao,Shuang-Nan Zhang +1 more
TL;DR: In this article, the authors obtained the dilaton black-hole solutions in the background of the de Sitter or anti-de Sitter universe, with the combination of three Liouville-type dilaton potentials.
Journal ArticleDOI
Modified Entropic Force
TL;DR: In this article, a modified entropic force formula is proposed to explain the acceleration of the Debye model in the strong field case, which is very similar to the one proposed in this paper.
Journal ArticleDOI
When scalar field is kinetically coupled to the Einstein tensor
Changjun Gao,Changjun Gao +1 more
TL;DR: In this paper, the authors explore the cosmic evolution of a scalar field with the kinetic term coupled to the Einstein tensor and find that, in the absence of other matter sources or in the presence of only pressureless matter, the scalar behaves as pressureless material and the sound speed of the scalars is vanishing.
