分布振子群体中的孤立子同步波

Solitary synchronization waves in distributed oscillators populations

L. A. Smirnov, G. V. Osipov, A. Pikovsky

摘要:

我们证明了存在孤立波的同步在一维阵列的相同的振子与拉普拉斯耦合。粗粒度的阵列描述导致复杂的序参量的非线性方程,在最简单的情况下,晶格方程类似于离散的非线性薛定谔晶格。接近完全同步,我们发现孤立波的序参量微扰,从已知的相位kovatons和kovatons,这些解决方案的数值扩展到全域的可能的同步水平。对于非全同振子,证明了耗散孤子的存在性。

英文摘要:

We demonstrate existence of solitary waves of synchrony in one-dimensional arrays of identical oscillators with Laplacian coupling. Coarse-grained description of the array leads to nonlinear equations for the complex order parameter, in the simplest case to lattice equations similar to those of the discrete nonlinear Schrodinger lattice. Close to full synchrony, we find solitary waves for the order parameter perturbatively, starting from the known phase compactons and kovatons; these solution are extended numerically to the full domain of possible synchrony levels. For non-identical oscillators, existence of dissipative solitons is demonstrated.
