Polarization modes of gravitational waves in scalar-tensor-Rastall theory
Yu-Zhi Fan, Xiao-Bin Lai, Yu-Qi Dong +1
Rastall theory, originally introduced in 1972, suggests a violation of the usual conservation law. We consider two generalizations of Rastall theory: Brans-Dicke-Rastall theory and…

Gravitational-wave effects in the most general vector-tensor theory
Yu-Qi Dong, Xiao-Bin Lai, Yu-Qiang Liu +1
In this paper, we establish a model-independent framework based on the Isaacson picture to analyze the gravitational-wave effects in the most general vector-tensor theory that yiel…

Polarization modes of gravitational waves in general Einstein-vector theory
Xiao-Bin Lai, Yu-Qi Dong, Yu-Qiang Liu +1
We study the polarization modes of gravitational waves in general Einstein-vector theory with an arbitrary constant background vector field under a Minkowski background. We compare…
