Chaotic dynamics of charged particles near weakly magnetized black holes in Einstein-ModMax Theory
Zijian Liu, Wenfu Cao
This paper presents a systematic study of the chaotic dynamics of charged test particles around purely magnetically charged black holes immersed in a uniform external magnetic fiel…
Time-reversed Shannon entropy as a chaos indicator for non-integrable systems
Wenfu Cao, Siyan Chen, Hongsheng Zhang
We propose a novel chaos indicator -- time-reversed Shannon entropy (TRSE) -- that leverages the interplay between time-reversal symmetry breaking and information entropy in curved…
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…
