耦合振子系统的平均场和平均振荡频率

Mean Field and Mean Ensemble Frequencies of a System of Coupled Oscillators

摘要:

我们研究了相互作用的相位振荡器,其平均场与其固有频率的平均值或模式不同。相关的不对称性导致宏观行波。我们表明,这些系统的平均合奏频率不同于他们的夹带频率。在某些情况下,这些频率的值与直觉相反,超出了固有频率的限制。结果表明,应该明确区分描述合作系统宏观动力学的两个变量。这对真实系统具有重要意义,其中参数的非平凡分布是常见的。

英文摘要:

We investigate interacting phase oscillators whose mean field is at a different frequency from the mean or mode of their natural frequencies. The associated asymmetries lead to a macroscopic travelling wave. We show that the mean ensemble frequency of such systems differs from their entrainment frequency. In some scenarios these frequencies take values that, counter-intuitively, lie beyond the limits of the natural frequencies. The results indicate that a clear distinction should be drawn between the two variables describing the macroscopic dynamics of cooperative systems. This has important implications for real systems where a non-trivial distribution of parameters is common.
