空间耦合相位振子的滞回特性

Hysteretic behavior of spatially coupled phase-oscillators

Eszter Fehér, Balázs Havasi-Tóth, Tamás Kalmár-Nagy

摘要:

受萤火虫群同步闪烁等生物系统相关现象的启发,我们研究了具有惯性的广义仓本模型下演化的相位振荡器网络。被认为是一个依赖于距离的,振荡器之间的空间耦合。选择具有有限核半径的零阶和一阶核函数来研究局部相互作用的影响。分析了不同核半径下耦合参数对同步的滞后动力学特性的影响。数值研究表明:(1)当耦合强度较小时,局域锁定团簇的形成;(2)当核半径较小时,滞后行为消失;(3)核半径与振子间最大距离的比值表征了网络的行为.

英文摘要:

Motivated by phenomena related to biological systems such as the synchronously flashing swarms of fireflies, we investigate a network of phase oscillators evolving under the generalized Kuramoto model with inertia. A distance-dependent, spatial coupling between the oscillators is considered. Zeroth and first order kernel functions with finite kernel radii were chosen to investigate the effect of local interactions. The hysteretic dynamics of the synchronization depending on the coupling parameter was analyzed for different kernel radii. Numerical investigations demonstrate that (1) locally locked clusters develop for small coupling strength values, (2) the hysteretic behavior vanishes for small kernel radii, (3) the ratio of the kernel radius and the maximal distance between the oscillators characterizes the behavior of the network.
