How Anti-de Sitter Black Holes Reach Thermal Equilibrium
Ru Ling, Hao Xu, Yen Chin Ong
It is commonly known in the literature that large black holes in anti-de Sitter spacetimes (with reflective boundary condition) are in thermal equilibrium with their Hawking radiat…
Quasinormal Modes of Analog Rotating Black Holes in 2-Dimensional Photon-Fluid Model
Hang Liu, Hong Guo, Ru Ling
It was recently found that the optical field fluctuations in self-defocusing media can be described by sound waves propagating in a two-dimensional photon-fluid. This photon-fluid…
A Vehicle Size-Based Dynamic Model of Artificial Driving Risk Potential Fields and Vehicle Interaction Analysis for Highway Driving
Ru Ling, Meng Li, Bowen Liu +1
Traditional driving risk potential field model generally assumes uniform vehicle sizes, which fails to reflect the heterogeneity in real-world traffic environment. This study aims…
Shadow and near-horizon characteristics of the acoustic charged black hole in curved spacetime
Ru Ling, Hong Guo, Hang Liu +2
In this paper, we first analyze the horizon structure of the acoustic charged black hole in curved spacetime, and then study its acoustic shadow as well as the near-horizon charact…
