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…
Dynamics of photons and shadows for black holes haired with parity-odd fields
Yang Huang, Dao-Jun Liu, Hongsheng Zhang
Strong self-gravitational fields enable the realization of macroscopic odd-parity quantum objects. Using ray-tracing methods, we systematically analyze the dynamics of photons and…
Spontaneous genesis of naked singularities through quantum-gravitational processes: conclusive evidence for violation of cosmic censorship
Yang Huang, Hongsheng Zhang
Cosmic censorship conjecture takes a pivotal status in general relativity. We demonstrate that quantum effects, Hawking effect together with Shwinger effect inevitably lead to viol…
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…
Quantum anomaly triggers the violation of scaling laws in gravitational system
Ya-Peng Hu, Yu-Sen An, Gao-Yong Sun +5
Scaling laws for critical phenomena take pivotal status in almost all branches of physics. However, as scaling laws are commonly guaranteed by the renormalization group theory, sys…
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…
