Noise-induced order

Noise-induced order is a mathematical phenomenon appearing in the Matsumoto-Tsuda[1] model of the Belosov-Zhabotinski reaction.

In this model, adding noise to the system causes a transition from a "chaotic" behaviour to a more "ordered" behaviour; this article was a seminal paper in the area and generated a big number of citations[2] and gave birth to a line of research in applied mathematics and physics.[3][4] This phenomenon was later observed in the Belosov-Zhabotinsky reaction.[5]

Mathematical backgroundEdit

Interpolating experimental data from the Belosouv-Zabotinsky reaction,[6] Matsumoto and Tsuda introduced a one dimensional model, a random dynamical system with uniform additive noise, driven by the map:

 

where

  •   (defined so that  ),
  •  , such that   lands on a repelling fixed point (in some way this is analogous to a Misiurewicz point)
  •   (defined so that  ).

This random dynamical system is simulated with different noise amplitudes using floating-point arithmetic and the Lyapunov exponent along the simulated orbits is computed; the Lyapunov exponent of this simulated system was found to transition from positive to negative as the noise amplitude grows.[1]

The behavior of the floating point system and of the original system may differ;[7] therefore, this is not a rigorous mathematical proof of the phenomenon.

A computer assisted proof of noise-induced order for the Matsumoto-Tsuda map with the parameters above was given in 2017.[8] In 2020 a sufficient condition for noise-induced order was given for one dimensional maps:[9] the Lyapunov exponent for small noise sizes is positive, while the average of the logarithm of the derivative with respect to Lebesgue is negative.
