摘要(Abstract):

研究发现在随机初始条件下,一维全同相振子系统在非局域不对称耦合作用下演化成的移动奇异态同步部分可移动.移动速度与不对称耦合强度线性相关.利用Ott-Antonsen假设方法理论上分析并证实了这一特性.
In this paper, we study the traveling chimera state of one-dimensional array of nonlocally coupled identical phase oscillators with asymmetric coupling under random initial conditions. It is found that the coherent groups can move and the velocity is linearly related to the asymmetric coupling. The results are confirmed by the theoretical analysis based on the Ott-Antonsen(OA) ansatz.
