Correlated parity violation in gravity and electromagnetism from five-dimensional spacetime
Haomin Rao, Yunlong Zheng, Qi-Zhe Hou +2
Parity violation in the gravitational and electromagnetic sectors has been extensively investigated, yet the two are conventionally treated as independent phenomena. This separatio…

Revisiting a parity violating gravity model without ghost instability: Local Lorentz covariance
Mingzhe Li, Haomin Rao, Yeheng Tong
Recently, based on the theory of teleparallel gravity, a simple and ghost free parity violating gravity model was proposed in [M. Li, H. Rao, and D. Zhao, J. Cosmol. Astropart. Phy…

Eddington-inspired Born-Infeld Gravity with Varying Cosmological Constant
Haomin Rao, Dehao Zhao
In this paper we modify the EiBI model to realize a varying cosmological constant which is determined by matter distribution. We find that the Newton's constant is also variable an…
