On the degrees of freedom of spatially covariant vector field theory
Shu-Yu Li, Xian Gao
We investigate a class of spatially covariant vector field theories on a flat background, where the Lagrangians are constructed as polynomials of first-order derivatives of the vec…

Scalar-induced gravitational waves in spatially covariant gravity
Jiehao Jiang, Jieming Lin, Xian Gao
We investigate scalar-induced gravitational waves (SIGWs) in the framework of spatially covariant gravity (SCG), a broad class of Lorentz-violating modified gravity theories respec…

Spatial covariant gravity with two degrees of freedom in the presence of an auxiliary scalar field: perturbation analysis
Zhi-Chao Wang, Xian Gao
We investigate a class of gravity theories respecting only spatial covariance, termed spatially covariant gravity, in the presence of an auxiliary scalar field. We examine the cond…
