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…
Braneworld sum rules and positive tension branes in a massive gravity
Ke Yang, Bao-Min Gu, Yi Zhong
By taking advantage of the braneworld sum rules, we explore the feasibility of constructing a flat 3-brane scenario consisting solely of positive tension branes in a 5D extension o…
Inflation with shallow dip and primordial black holes
Bao-Min Gu, Fu-Wen Shu, Ke Yang
Primordial black holes may arise through ultra slow-roll inflation. In this work we study a toy model of ultra slow-roll inflation with a shallow dip. The ultra slow-roll stage enh…
Localization of matter fields on a chameleon brane
Yi Zhong, Ke Yang
In this work, we address the localization problem of vector field in the chameleon braneworld and investigate the localization of various matter fields. The conditions for localizi…
Thick branes in Born-Infeld determinantal gravity in Weitzenböck spacetime
Ke Yang, Hao Yu, Yi Zhong
By adopting the idea of Born-Infeld electromagnetism, the Born-Infeld determinantal gravity in Weitzenböck spacetime provides a way to smooth the Big Bang singularity at the classi…
A braneworld model in a massive gravity
Ke Yang, Shi-Fa Guo, Bao-Min Gu
A Randall-Sundrum-like braneworld scenario is constructed in a 5D extension of the Lorentz-violating massive gravity. The gauge hierarchy problem is solved in current model. The li…
