First laws of thermodynamics in IR Modified Hǒrava-Lifshitz gravity
Mengjie Wang, Jiliang Jing, Chikun Ding +1
We study the first law of thermodynamics in IR modified Hǒrava-Lifshitz spacetime. Based on the Bekenstein-Hawking entropy, we obtain the integral formula and the differential form…

Emergent universe from the Hořava-Lifshitz gravity
Puxun Wu, Hongwei Yu
We study the stability of the Einstein static universe in the Hořava-Lifshitz (HL) gravity and a generalized version of it formulated by Sotiriou, Visser and Weifurtner. We find th…
Improved parametrization of the growth index for dark energy and DGP models
Jiliang Jing, Songbai Chen
We propose two improved parameterized form for the growth index of the linear matter perturbations: (I) and (II) $γ(z)=γ_0+γ_1 \frac{z}{z+1}…

The entanglement of the coupled massive scalar field in the spacetime of a Garfinkle-Horowitz-Strominger(GHS) dilaton black hole has been investigated. It is found that the entangl…
Projective measurements and generation of entangled Dirac particles in Schwarzschild Spacetime
Jieci Wang, Qiyuan Pan, Jiliang Jing
It is shown that the projective measurements made by Bob who locates near the event horizon of the Schwarzschild black hole will create entangled particles detected by Alice who st…
Timelike Geodesic Motion in Horava-Lifshitz Spacetime
Juhua Chen, Yongjiu Wang
Recently Hoava proposed a non-relativistic renormalisable theory of gravitation. When restricted to satisfy the condition of detailed balance, this theory is intimately…
