标题： Frequency Synchronization Induced by Frequency Detuning

摘要： 人们普遍认为，在可比较的条件下，相同的系统倾向于表现出相似的行为。然而，对于通过网络相互作用的系统，对称性破缺可能导致这种期望不成立的情况。突出的例子是多稳态相位振荡器网络中的 chimera 状态。 在这里，我们展示了对于这类网络的一个广泛类别，当相同的振子被调整为具有不同的固有频率时，异步状态可以转换为频率同步状态。重要的是，我们展示了频率同步是在固有频率失谐范围内实现的，因此是一种稳健的效果。 这些结果得到了理论、仿真和电化学振子实验的支持，揭示了一个反直觉的机会，即利用参数异质性来促进同步。 显示英文摘要

摘要： It is widely held that identical systems tend to behave similarly under comparable conditions. Yet, for systems that interact through a network, symmetry breaking can lead to scenarios in which this expectation does not hold. Prominent examples are chimera states in multistable phase-oscillator networks. Here, we show that for a broad class of such networks, asynchronous states can be converted into frequency-synchronized states when identical oscillators are detuned to have different intrinsic frequencies. Importantly, we show that frequency synchronization is achieved over a range of intrinsic frequency detuning and is thus a robust effect. These results, which are supported by theory, simulations, and electrochemical oscillator experiments, reveal a counterintuitive opportunity to use parameter heterogeneity to promote synchronization.
