Gravitational Lensing of Gravitational Waves: Spin-wave Optics through Black Hole Scattering
Zhao Li, Shaoqi Hou, Wen Zhao
Gravitational-wave (GW) scattering in strong gravitational fields is a central problem in GW lensing. Yet, conventional treatments based on asymptotic expansions suffer from diverg…

Rigorous calculation of scalar scattering in Schwarzschild background: the convergence of partial-wave series and Poisson spot
Zhao Li, Wen Zhao
Black hole (BH) perturbation theory and the scattering models provide a powerful framework for studying gravitational lensing at the wave-optics level. However, conventional calcul…

Dynamics and gravitational radiation of binaries with spin precession and eccentricity in dynamical Chern-Simons gravity
Zhao Li, Wen Zhao
Testing parity symmetry constitutes a critical aspect in gravitational physics. As a representative parity-violating theory, dynamical Chern-Simons (dCS) gravity has attracted sign…
