Quasiperiodic Skin Criticality in an Exactly Solvable Non-Hermitian Quasicrystal
Zhangyuan Chen, Muhammad Idrees, Ying Yang +2
Critical states in quasiperiodic systems defy the conventional dichotomy between extended and localized states. In this work, we demonstrate that non-Hermiticity fundamentally resh…
Variation of entropy in the Duffing system with the amplitude of the external force
Junfeng Cheng, Xiao-Song Yang
In this paper, we revisit the well-known perturbed Duffing system and investigate its chaotic dynamics by means of numerical Runge--Kutta method based on topological horseshoe theo…
Incomplete crossing and semi-topological horseshoes
Junfeng Cheng, Xiao-Song Yang
This paper enriches the topological horseshoe theory using finite subshift theory in symbolic dynamical systems, and develops an elementary framework addressing incomplete crossing…
Probability of constructing prediction model for observable of a dynamical process via time series
Xiao-Song Yang
One fundamental problem in studying dynamical process is whether it is possible and how to construct prediction model for an unknown system via sampled time series, especially in t…
