Thick brane in Rastall gravity
Yi Zhong, Ke Yang, Yu-Xiao Liu
In this work, thick branes in Rastall gravity are investigated. Three types of maximally symmetric thick brane models are constructed and the linear tensor perturbation is analyzed…
First-order formalism and thick branes in mimetic gravity
Qun-Ying Xie, Qi-Ming Fu, Tao-Tao Sui +2
In this paper, we investigate thick branes generated by a scalar field in mimetic gravity theory. By introducing two auxiliary super-potentials, we transform the second-order field…
Gravitational resonances in mimetic thick branes
Yi Zhong, Yu-Peng Zhang, Wen-Di Guo +1
In this work, we investigate gravitational resonances in both single and double mimetic thick branes, which can provide a new way to detect the extra dimension. For the single bran…
Inflation in mimetic f(G) gravity
Yi Zhong, Diego Saez-Chillon Gomez
Mimetic gravity is analysed in the framework of some extensions of General Relativity, where a function of the Gauss-Bonnet invariant in four dimensions is considered. By assuming…
De Sitter and power-law solutions in some models of modified gravity
Yi Zhong, Emilio Elizalde
Inspired by some recent works of Lovelock Brans-Dicke gravity and mimetic gravity, cosmology solutions in extensions of these two modified gravities are investigated. A non-local t…
Time-Dependent Scalar Fields in Modified Gravities in a Stationary Spacetime
Yi Zhong, Bao-Min Gu, Shao-Wen Wei +1
Most no-hair theorems involve the assumption that the scalar field is independent of time. Recently in [Phys. Rev. D90 (2014) 041501(R)] the existence of time-dependent scalar hair…
