Entrainment and Noise Synchronization in Coupled Chemical Oscillators

摘要

Entrainment phenomena and nose synchronization (NS) in nonliear chemicla oscillators, coupled through diffusions, are reported. We have realized a discrete osicllator system in Belousov-Zhabotinsky (BZ) reaction by use of cation-exchanged beads in aqueous solution. For the entrainment, a nonlinear relationship between the coupled osicillators is observed and the entrainment width is determined. The noise intensity for the most broad entrainment width is obtained. The NS phenomenon is clearly observed.
