长程相互作用振子链的动力学:从同步到混沌

Dynamics of the Chain of Oscillators with Long-Range Interaction: From Synchronization to Chaos

G. M Zaslavsky, M. Edelman, V. E. Tarasov

摘要:

我们考虑一类具有1/l^{1+alpha}型长程相互作用的非线性振子链,其中l是振子之间的距离,0< alpha <2。在连续极限下,系统的动力学行为可用复系数的Ginzburg-Landau方程描述。这样一个系统有一个新的参数α,负责介质的复杂性,并强烈影响可能的制度的动态。我们研究了不同的时空模式的动态依赖于α和显示从同步的运动到广谱振荡和混沌的过渡。

英文摘要:

We consider a chain of nonlinear oscillators with long-range interaction of the type 1/l^{1+alpha}, where l is a distance between oscillators and 0< alpha <2. In the continues limit the system's dynamics is described by the Ginzburg-Landau equation with complex coefficients. Such a system has a new parameter alpha that is responsible for the complexity of the medium and that strongly influences possible regimes of the dynamics. We study different spatial-temporal patterns of the dynamics depending on alpha and show transitions from synchronization of the motion to broad-spectrum oscillations and to chaos.
