Linear Perturbations and Stability Analysis in Braneworld Scenario
Ju-Ying Zhao, Mao-Jiang Liu, Ke Yang
We conduct a detailed analysis of the full linear perturbations in the braneworld scenario within gravity. By decomposing the perturbations of the theory into the scalar, tr…

Electrically charged black holes in gravity with a background Kalb-Ramond field
Zheng-Qiao Duan, Ju-Ying Zhao, Ke Yang
We derive the exact solutions for electrically charged black holes both in the absence and presence of a cosmological constant in the gravitational theory with Lorentz violation in…

Static and spherically symmetric black holes in gravity with a background Kalb-Ramond field
Ke Yang, Yue-Zhe Chen, Zheng-Qiao Duan +1
The Lorentz symmetry of gravity is spontaneously broken when the nonminimally coupled Kalb-Ramond field acquires a nonzero vacuum expectation value. In this work, we present exact…
