在一个圆形容器中的漂浮在水面上的樟脑圆盘系统中发现了一种新的集体运动模式。该模式是通过调节圆盘的数目来诱导的。已知单个或几个圆盘在水面上连续移动。相反，当存在许多圆盘时，运动停止，并且圆盘通过排斥相互作用形成有序的空间图案。在这里，我们发现了第三种模式，出现在一个中间的磁盘数量，其中不活跃和活跃的运动阶段交替非周期性。这种新模式随着磁盘数量的增加而呈现同步性。
A new mode of collective motion was discovered in a system of camphor disks floating on the water surface in a circular chamber. The mode was induced by tuning the number of the disks. A single or few disks are known to continuously move on the water surface. Conversely, when many disks are present, motion comes to a stop and the disks form ordered spatial patterns by repulsive interaction. Here we found the third mode that emerged at an intermediate disk number, in which inactive and active motion phases alternated non-periodically. This new mode exhibited synchronization as the disk number increased.
