Stable massless scalar polarization of f(R) gravity
Xin-Dong Du, Peng-Cheng Li
Polarization is a prominent feature of gravitational wave observations and can be used to distinguish between different modified gravity theories. Compared to General Relativity, f…

Quasinormal modes of accelerating spacetime
Tao Zhou, Peng-Cheng Li
We calculate the exact values of the quasinormal frequencies for massless perturbations with spin moving in pure accelerating spacetime. We use two different methods to tr…
