Motion of spinning particles in the Kerr-Newman black hole exterior
Yi-Ping Chen, Tien Hsieh, Da-Shin Lee
The motion of a spinning particle in the exterior of a Kerr-Newman black hole is studied. The dynamics is governed by the Mathisson-Papapetrou equations in the pole-dipole approxim…

Regge poles of analogous rotating black holes in binary Bose-Einstein condensates: The gapped excitations
Wei-Can Syu, Tien Hsieh, Da-Shin Lee
In this paper, we study the spectrum of the Regge poles (RPs), which are the counterparts of quasinormal modes, in a draining bathtub vortex within a two-component Bose-Einstein co…

Dynamics of spinning particles in Reissner-Nordström black hole exterior
Siang-Yao Ciou, Tien Hsieh, Da-Shin Lee
We study the orbits of a spinning particle in the Reissner-Nordström black hole exterior through the spin-curvature coupling to leading order in its spin. The dynamics is governed…
