Pre-inflationary universe in loop quantum cosmology

- Tao Zhu, A. Wang, G. Cleaver, K. Kirsten, Qin Sheng
- Physics
- 21 May 2017

The evolutions of the flat FLRW universe and its linear perturbations are studied systematically in the dressed metric approach of LQC. When it is dominated by the kinetic energy of the inflaton at… Expand

LETTER: Generalized Vaidya Solutions

A large family of solutions, representing, ingeneral, spherically symmetric Type II fluid, ispresented, which includes most of the known solutions tothe Einstein field equations, such as, the… Expand

Born-Infeld black holes in (A)dS spaces

- R. Cai, Da-Wei Pang, A. Wang
- Physics
- 14 October 2004

We study some exact solutions in a D(greater than or equal to4)-dimensional Einstein-Born-Infeld theory with a cosmological constant. These solutions are asymptotically de Sitter or anti-de Sitter,… Expand

Hořava gravity at a Lifshitz point: A progress report

- A. Wang
- Physics
- 21 January 2017

Hořava’s quantum gravity at a Lifshitz point is a theory intended to quantize gravity by using traditional quantum field theories. To avoid Ostrogradsky’s ghosts, a problem that has been facing in… Expand

Generalized instantaneous modes in higher-order scalar-tensor theories

- A. Felice, D. Langlois, S. Mukohyama, K. Noui, A. Wang
- Physics
- 16 March 2018

We consider higher-order, scalar-tensor theories which appear degenerate when restricted to the unitary gauge but are not degenerate in an arbitrary gauge. We dub them U-degenerate theories. We… Expand

Post-Newtonian approximations in the Hořava-Lifshitz gravity with extra U(1) symmetry

- Kai Lin, S. Mukohyama, A. Wang, Tao Zhu
- Physics
- 24 October 2013

In this paper, we first propose a universal coupling between the gravity and matter in the framework of the Ho\v{r}ava-Lifshitz theory of gravity with an extra U(1) symmetry for both the projectable… Expand

Current constraints on interacting holographic dark energy

- Q. Wu, Y. Gong, A. Wang, J. Alcaniz
- Physics
- 7 May 2007

Abstract Although there is mounting observational evidence that the cosmic expansion is undergoing a late-time acceleration, the physical mechanism behind such a phenomenon is yet unknown. In this… Expand

Universal features of quantum bounce in loop quantum cosmology

- Tao Zhu, A. Wang, K. Kirsten, G. Cleaver, Qin Sheng
- Physics
- 20 July 2016

Abstract In this Letter, we study analytically the evolutions of the flat Friedmann–Lemaitre–Robertson–Walker (FLRW) universe and its linear perturbations in the framework of the dressed metric… Expand

Thermodynamics and stability of hyperbolic charged black holes

In AdS space the black hole horizon can be a hypersurface with a positive, zero, or negative constant curvature, resulting in different horizon topology. Thermodynamics and stability of black holes… Expand
