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…
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…
Polarization modes of gravitational waves in general modified gravity: General metric theory and general scalar-tensor theory
Yu-Qi Dong, Yu-Qiang Liu, Yu-Xiao Liu
In this paper, we establish a unified parameterized framework for analyzing the polarization modes of gravitational waves in the general metric theory (gravity is only described by…
Polarization modes of gravitational waves in generalized Proca theory
Yu-Qi Dong, Yu-Qiang Liu, Yu-Xiao Liu
In this paper, we study polarization modes of gravitational waves in generalized Proca theory in the homogeneous and isotropic Minkowski background. The results show that the polar…
Constraining Palatini-Horndeski theory with gravitational waves after GW170817
Yu-Qi Dong, Yu-Qiang Liu, Yu-Xiao Liu
In this paper, we investigate the possible parameter space of Palatini-Horndeski theory with gravitational waves in a spatially flat Universe. We find that if the theory satisfies…
Classification of Gravitational Waves in Higher-dimensional Space-time and Possibility of Observation
Yu-Qiang Liu, Yu-Qi Dong, Yu-Xiao Liu
The direct detection of gravitational waves opens the possibility to test general relativity and its alternatives in the strong field regime. Here we focus on the test of the exist…
