三维空间中运动振子的同步

Synchronization of moving oscillators in three dimensional space

Soumen Majhi, Dibakar Ghosh

摘要:

我们研究了一个动态网络的宏观行为,该网络由一组随机游走者之间的相互作用的时间演化布线组成。我们假设每个步行者(代理)有一个振荡器,并显示,根据相互作用的性质,同步出现在每个单独的振荡器被允许在这样一个随机行走的方式在三维空间的有限区域移动。在这里,每个振子的视觉范围决定了它与之相互作用的振子的数量。振荡器之间的实时相互作用是中间类型的(即,既不是局部的也不是全局的)并且可以是双向的也可以不是双向的。利用线性稳定性分析,我们解析地导出了耦合强度依赖于密度的同步阈值,并数值验证了所得到的解析结果。此外,我们探讨了盆地稳定性的概念,一个非线性措施的基础上的体积盆地的吸引力,研究如何稳定的同步状态下大扰动。同步现象进行了分析,采取极限环和混沌振荡器的参数之间的相互作用强度k的步行者,运动速度v和视觉范围r的宽范围内。

英文摘要:

We investigate macroscopic behavior of a dynamical network consisting of a time-evolving wiring of interactions among a group of random walkers. We assume that each walker (agent) has an oscillator and show that depending upon the nature of interaction, synchronization arises where each of the individual oscillators are allowed to move in such a random walk manner in a finite region of three dimensional space. Here the vision range of each oscillator decides the number of oscillators with which it interacts. The live interaction between the oscillators is of intermediate type ( i.e., not local as well as not global) and may or may not be bidirectional. We analytically derive density dependent threshold of coupling strength for synchronization using linear stability analysis and numerically verify the obtained analytical results. Additionally, we explore the concept of basin stability, a nonlinear measure based on volumes of basin of attractions, to investigate how stable the synchronous state is under large perturbations. The synchronization phenomenon is analyzed taking limit cycle and chaotic oscillators for wide ranges of parameters like interaction strength k between the walkers, speed of movement v and vision range r.
