Chaotic motion of scalar particle coupling to Chern-Simons invariant in Kerr black hole spacetime
Xuan Zhou, Songbai Chen, Jiliang Jing
We present firstly the equation of motion for the test scalar particle coupling to the Chern-Simons invariant in Kerr black hole spacetime by the short-wave approximation. We have…
