Synchronization of intercommunicating individual oscillators is an important form of collective behavior used in nature as a mechanism to face dangers, act collectively, and communicate. The involvement of the medium where oscillators exist is an important ingredient. Because of their nature and their multiple different components, the medium and the environment are often perceived as stochastic relative to the deterministic nature of the individuals on some scale. This injects energy/matter into the system in ways that can enhance or de-enhance communication in a stochastic manner. Here we experimentally consider a large number of coupled nonlinear-chemical oscillators under the effect of a controlled normally distributed noise. Experiments show that the collective behavior of the oscillator is triggered by this stochastic perturbation, and we observe the dependence on the noise parameters. Our results point to the potential use of environmental fluctuations in determining the emergence and properties of collective behaviors in complex systems.
相互通信的个体振荡器同步是自然界中一种重要的集体行为形式，用作面对危险、集体行动和通信的机制。振荡器所处介质的参与是一个重要因素。由于介质和环境的性质及其多个不同组成部分，在某些尺度上，相对于个体的确定性本质，介质和环境通常被视为具有随机性。这以随机方式向系统注入能量/物质，从而增强或减弱通信。在此，我们通过实验研究了大量耦合非线性化学振荡器在受控正态分布噪声作用下的情况。实验表明，振荡器的集体行为由这种随机扰动触发，并且我们观察到了对噪声参数的依赖性。我们的结果表明，环境波动在确定复杂系统中集体行为的出现和特性方面具有潜在用途。
