We study a model of nonidentical swarmalators, generalizations of phase oscillators that both sync in time and swarm in space. The model produces four collective states: asynchrony, sync clusters, vortexlike phase waves, and a mixed state. These states occur in many real-world swarmalator systems such as biological microswimmers, chemical nanomotors, and groups of drones. A generalized Ott-Antonsen ansatz provides the first analytic description of these states and conditions for their existence. We show how this approach may be used in studies of active matter and related disciplines.
我们研究了一个非同源 swarmalators 模型，这是一种时间同步和空间群集的相振荡器的推广。该模型产生了四种集体状态：异步、同步簇、类涡旋相位波和混合状态。这些状态存在于许多现实世界的 swarmalator 系统中，如生物微泳者、化学纳米马达和无人机群。广义 Ott-Antonsen 假设提供了对这些状态及其存在条件的第一个解析描述。我们展示了如何在活性物质和相关学科的研究中使用这种方法。
