Disorder Parameter for Chaos

Yoshitsugu Oono, Tohru Kohda

Research output: Contribution to journalArticlepeer-review


As a possible dual concept of the order parameter in the theory of phase transition, it is desirable to introduce the disorder parameter for chaos. A mathematically well-defined disorder parameter is proposed, which is presumably identical with the Kolumogorov entropy, though rigorous proof is not yet obtained. Possible potential applications of the disorder parameter to the analyses of time-series are given.
