Thick braneworld model in nonmetricity formulation of general relativity and its stability
Qi-Ming Fu, Li Zhao, Qun-Ying Xie
In this paper, we study the thick brane system in the so-called gravity, where the gravitational interaction was encoded by the nonmetricity like scalar curvature in…
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…
Flat and bent branes with inner structure in two-field mimetic gravity
Qian Xiang, Yi Zhong, Qun-Ying Xie +1
Inspired by the work [Eur. Phys. J. C 78 (2018) 45], we study the linear tensor perturbation of both the flat and bent thick branes with inner structure in two-field mimetic gravit…
Generalized geometrical coupling for vector field localization on thick brane in asymptotic Anti-de Sitter spacetime
Tao-Tao Sui, Wen-Di Guo, Qun-Ying Xie +1
It is known that a five-dimensional free vector field cannot be localized on Randall-Sundrum (RS)-like thick branes, namely, the thick branes embedded in asymptotic Anti-de…
Fermion Localization and Degenerate Resonances on Brane Array
Qun-Ying Xie, Zhen-Hua Zhao, Jie Yang +1
In this work, we consider the multi-wall braneworld arisen from multi-scalar fields, and investigate the localization and resonances of spin-1/2 fermion on the multi-walls. We buil…
