Gravitational Wave Birefringence in Symmetron Cosmology
Ze-Xuan Xiong, Da Huang
The symmetron is a light scalar which provides a screening mechanism so as to evade the strong constraints from local gravity tests. In order to achieve this goal, a symmetry…

Gravitational Wave Birefringence from Fuzzy Dark Matter
Da Huang, Ze-Xuan Xiong, Lei-Jian Wang
Gravitational wave (GW) birefringence is a remarkable phenomenon that can be used to test the parity violation in gravity. By coupling the fuzzy dark matter (FDM) scalar to the gra…
