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…
Parity violating scalar-tensor model in teleparallel gravity and its cosmological application
Haomin Rao, Dehao Zhao
The parity violating model based on teleparallel gravity is a competitive scheme for parity violating gravity, which has been preliminary studied in the literature. To further inve…
Irregular universe in the Nieh-Yan modified teleparallel gravity
Mingzhe Li, Haomin Rao
The Nieh-Yan modified teleparallel gravity is a model which modifies the general relativity equivalent teleparallel gravity by a coupling between the Nieh-Yan density and an axion-…
Extensions of two-field mimetic gravity
Yunlong Zheng, Haomin Rao
Two-field mimetic gravity was recently realized by looking at the singular limit of the conformal transformation between the auxiliary metric and the physical metric with two scala…
Ghost instability in the teleparallel gravity model with parity violations
Mingzhe Li, Zhihao Li, Haomin Rao
In this paper we consider the parity violating gravity model within the framework of teleparallel gravity. The parity violations are caused by the couplings of a scalar field to th…
Gravitational leptogenesis in teleparallel and symmetric teleparallel gravities
Mingzhe Li, Yicen Mou, Haomin Rao +1
In this paper, we consider the possibilities of generating baryon number asymmetry in thermal equilibrium within the frameworks of teleparallel and symmetric teleparallel gravities…
Parametrized post-Newtonian limit of the Nieh-Yan modified teleparallel gravity
Haomin Rao
The recently proposed Nieh-Yan modified teleparallel gravity is a parity-violating gravity model that modifies the general relativity equivalent teleparallel gravity by a Nieh-Yan…
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…
Conformal invariant cosmological perturbations via the covariant approach: multicomponent universe
Yunlong Zheng, Yicen Mou, Haomin Rao +1
In recent years there has been a lot of interest in discussing frame dependences/independences of the cosmological perturbations under the conformal transformations. This problem h…
