Onset of Chaos and Orbital Instabilities around Rotating Weyl Black Holes

This study demonstrates that in rotating Weyl conformal gravity black holes, increasing spin and higher-order curvature corrections ($\xi$ and $\gamma$) destabilize photon orbits by breaking invariant tori and inducing a transition from regular to chaotic dynamics, thereby offering nonlinear photon motion as a potential probe for deviations from General Relativity in strong gravitational fields.
