| Abstract(in English) | In uncoupled oscillatory systems, it is widely known that common noise input can induce chaotic synchronization. However, while noise can ``enhance'' a degree of chaotic synchronization, few studies report the chaotic synchronization purely ``induced'' by external noise in coupled oscillatory systems. In this study, a solvable model for mean-field coupled limit cycle oscillators under the influence of independent noise is considered. The model consists of the two types of limit cycle oscillators with different native frequencies. We analytically and numerically show that the model exhibits chaotic synchronization purely induced by external noise. |
