要旨
Pattern formation induced by noise is a celebrated phenomenon in diverse experimental and numerical systems. Here we report experiments with the chlorine dioxide-iodine-malonic acid reaction (CDIMA) when illuminated with spatio-temporal stochastic intensity in the vicinity of the Hopf and Turing codimension-two-bifurcation. A noise-driven phenomenon of attenuation of oscillations is found. Numerical simulations confirm these results and farther away from the Turing-Hopf-boundary permit to unveil a true noise-mediated selection mechanism of Turing patterns over oscillatory modes.
