空间扩展振子网络中的嵌合体状态使一些振子同步，而其余振子则异步。这些状态主要在非局域耦合网络中进行研究，最近在全局耦合网络中进行了研究。在这里，我们提出了三个网络，只有本地耦合（扩散，最近的邻居），这是数值上发现支持嵌合体状态。其中一个网络使用连续极限中的自洽性参数进行分析，这用于找到参数空间中嵌合体状态存在的边界。
Chimera states in spatially extended networks of oscillators have some oscillators synchronized while the remainder are asynchronous. These states have primarily been studied in networks with nonlocal coupling, and more recently in networks with global coupling. Here, we present three networks with only local coupling (diffusive, to nearest neighbors) which are numerically found to support chimera states. One of the networks is analyzed using a self-consistency argument in the continuum limit, and this is used to find the boundaries of existence of a chimera state in parameter space.
