Matching McVittie spacetimes
Jining Tang, Yang Huang, Hongsheng Zhang
Gravitational collapse and bubble evolution in the asymptotical Friedmann-Lemaitre-Robertson-Walker (FLRW) Universe is an intriguing and intricate problem. We systematically analyz…
Mutual Information for particle pair and its application to diagnose Chaos in Curved Spacetime
Wenfu Cao, Yang Huang, Hongsheng Zhang
We propose the concept of mutual information for particle pair (MIPP) in curved spacetime, and show that MIPP has potential to be a proper chaos indicator. We tested this method in…
Screen chaotic motion by Shannon entropy in curved spacetimes
Wenfu Cao, Yang Huang, Hongsheng Zhang
We find a novel characteristic for chaotic motion by introducing Shannon entropy for periodic orbits, quasiperiodic orbits, and chaotic orbits.We compare our approach with the prev…
Lensing and light rings of parity-odd rotating boson stars
Yang Huang, Dao-Jun Liu, Hongsheng Zhang
We obtain the first image of a parity-odd celestial body. Recently, an intriguing parity-odd rotating boson star was proposed. We investigate the lensing effects of these stars in…
