We study the dynamics of nonlinear oscillators coupled through environmental diffusive coupling. The interaction between the dynamical systems is maintained through its agents which, in turn, interact globally with each other in the common dynamical environment. We show that this form of coupling scheme can induce an important transition like phase-flip transition as well transitions among oscillation quenching states in identical limit-cycle oscillators. This behavior is analyzed in the parameter plane by analytical and numerical studies of specific cases of the Stuart-Landau oscillator and van der Pol oscillator. Experimental evidences of the phase-flip transition and quenching states are shown using an electronic version of the van der Pol oscillators.
我们研究了通过环境扩散耦合的非线性振荡器的动力学。动力系统之间的相互作用通过其主体得以维持,这些主体进而在共同的动力环境中彼此进行全局相互作用。我们表明,这种耦合方案形式能够在相同的极限环振荡器中引发诸如相位翻转转变以及振荡猝灭状态之间的转变等重要转变。通过对斯图尔特 - 兰道振荡器和范德波尔振荡器的特定情况进行解析和数值研究,在参数平面中分析了这种行为。使用范德波尔振荡器的电子版本展示了相位翻转转变和猝灭状态的实验证据。
