We study a population of swarmalators (swarming/mobile oscillators) which run on a ring and are subject to random pinning. The pinning represents the tendency of particles to stick to defects in the underlying medium which competes with the tendency to sync and swarm. The result is rich collective behavior. A highlight is low dimensional chaos which in systems of ordinary, Kuramoto-type oscillators is uncommon. Some of the states (the phase wave and split phase wave) resemble those seen in systems of Janus matchsticks or Japanese tree frogs. The others (such as the sync and unsteady states) may be observable in systems of vinegar eels, electrorotated Quincke rollers, or other swarmalators moving in disordered environments.
我们研究了一群在环形上运行的群体（群体/移动振荡器），它们受到随机钉扎的影响。钉扎表示粒子倾向于粘在基础介质中的缺陷上，这与同步和群体的趋势相竞争。其结果是丰富的集体行为。一个亮点是低维混沌，在普通的 Kuramoto 型振荡器系统中很少见。一些状态（相波和分裂相波）类似于在 Janus 火柴棍或日本树蛙系统中看到的状态。其他状态（如同步和不稳定状态）可能在醋鳗、电旋转 Quincke 滚轮或其他在无序环境中移动的群体中观察到。
