Throat effects on strong gravitational lensing in Kerr-like wormholes

Tien Hsieh, Da-Shin Lee, Chi-Yong Lin

We study strong gravitational lensing by a specific one-parameter extension of Kerr spacetime, a Kerr-like wormhole, characterized by a single parameter specifying the throat's loc…

Inspiral and Plunging Orbits in Kerr-Newman Spacetimes

Yu-Chung Ko, Da-Shin Lee, Chi-Yong Lin

We present the analytical solutions for the trajectories of particles that spiral and plunge inward the event horizon along the timelike geodesics following general non-equatorial…

Homoclinic orbits in Kerr-Newman black holes

Yi-Ting Li, Chen-Yu Wang, Da-Shin Lee +1

We present the exact solutions of the homoclinic orbits for the timelike geodesics of the particle on the general nonequatorial orbits in the Kerr-Newman black holes. The homoclini…

Null and time-like geodesics in Kerr-Newman black hole exterior

Chen-Yu Wang, Da-Shin Lee, Chi-Yong Lin

We study the null and time-like geodesics of the light and the neutral particles respectively in the exterior of Kerr-Newman black holes. The geodesic equations are known to be wri…

Analogous Hawking radiation and quantum entanglement in two-component Bose-Einstein condensates: the gapped excitations

Wei-Can Syu, Da-Shin Lee, Chi-Yong Lin

The condensates of cold atoms at zero temperature in the tunable binary Bose-Einstein condensate system are studied with the Rabi transition between atomic hyperfine states where t…

Gravitational time delay effects by Kerr and Kerr-Newman black holes in strong field limits

Tien Hsieh, Da-Shin Lee, Chi-Yong Lin

We study the time delay between two relativistic images due to strong gravitational lensing of the light rays caused by the Kerr and Kerr-Newman black holes. The trajectories of th…
