Tensor Perturbations and Thick Branes in Higher-dimensional Gravity
Zheng-Quan Cui, Zi-Chao Lin, Jun-Jie Wan +2
We study brane worlds in an anisotropic higher-dimensional spacetime within the context of gravity. Firstly, we demonstrate that this spacetime with a concrete metric ansatz…
Equivalence of solutions between the four-dimensional novel and regularized EGB theories in a cylindrically symmetric spacetime
Zi-Chao Lin, Ke Yang, Shao-Wen Wei +2
Recently, a novel four-dimensional Einstein-Gauss-Bonnet (EGB) theory was presented to bypass the Lovelock's theorem and to give nontrivial effects on the four-dimensional local gr…
Constraint on the radius of five-dimensional dS spacetime with GW170817 and GRB 170817A
Zi-Chao Lin, Hao Yu, Yu-Xiao Liu
The recent detections of the gravitational wave (GW) event GW170817 and its electromagnetic counterpart GRB 170817A produced by a binary neutron star (NS) merger is a new milestone…
Gravitational waves and extra dimensions: a short review
Hao Yu, Zi-Chao Lin, Yu-Xiao Liu
We give a brief review on the recent development of gravitational waves in extra-dimensional theories of gravity. Studying extra-dimensional theories with gravitational waves provi…
Braneworld in Gravity Theory with Noncanonical Scalar Matter Field
Jian Wang, Wen-Di Guo, Zi-Chao Lin +1
In this paper, we investigate the braneworld scenario in gravity with a -field as the background field. We consider various different specific forms of gravity and…
Constraints on generalized Eddington-inspired Born-Infeld branes
Zi-Chao Lin, Ke Yang, Yu-Peng Zhang +2
The Palatini gravity is a generalized theory of the Eddington-inspired Born-Infeld gravity, where is an auxiliary tensor…
