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…
