Entanglement and firewalls in quantum circuit model of black hole evaporation

Yi-Chen Lu, Tien Hsieh, Da-Shin Lee

We reexamine the quantum circuit model of black hole evaporation proposed in a previous work (Class. Quantum Grav. 35, 235013, 2018) [1]. This tripartite model incorporates the fol…

Analytical solutions for timelike orbits around Damour-Solodukhin wormholes

Shao-Chen Ho, Yo-Chung Ko, Tien Hsieh +1

We investigate timelike geodesics around Damour-Solodukhin wormholes, which are Schwarzschild-like geometries characterized by a deformation parameter that determines the radi…

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…

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…
