Dynamical Love numbers of analogue rotating black and white holes
Satadal Datta, Wei-Can Syu, Da-Shin Lee
We calculate the dynamical tidal response coefficients (TRCs) of 2+1D analogue black and white holes generated by draining and fountaining bathtub flows, respectively. The paramete…
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 radiu…
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…
Null geodesics in extremal Kerr-Newman black holes
Bo-Ruei Chen, Tien Hsieh, Da-Shin Lee
We study the null geodesics in the extremal Kerr-Newman exterior. We clarify the roots of the radial potential and obtain the parameter space of the azimuthal angular momentum and…
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…
Acoustic quasibound states and tachyonic instabilities from binary Bose-Einstein condensates
Wei-Can Syu, Da-Shin Lee
We consider two-component Bose-Einstein condensates (BECs) and introduce the BEC vortex in dimensions. We focus on two types of gapped excitations induced by the modes of two…
