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…
Weak deflection angle by electrically and magnetically charged black holes from nonlinear electrodynamics
Qi-Ming Fu, Li Zhao, Yu-Xiao Liu
Nonlinear electrodynamic (NLED) theories are well-motivated for their extensions to classical electrodynamics in the strong field regime, and have been extensively investigated in…
Thick brane in reduced Horndeski theory
Qi-Ming Fu, Hao Yu, Li Zhao +1
Horndeski theory is the most general scalar-tensor theory retaining second-order field equations, although the action includes higher-order terms. This is achieved by a special cho…
