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…

Hereditary Effects and New Optical Properties of Nonlinear Gravitational Waves
Yu-Qiang Liu, Yu-Qi Dong, Yu-Xiao Liu
We investigate new optical effects of nonlinear gravitational waves that arise from hereditary effects. Firstly, we show that the amplitude of continuous plane waves has a heredita…

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…
