论文摘要
我们研究了障碍对Vicsek模型框架中自我推进对象集体运动的影响。障碍物以平方晶格排列并具有圆形形状。我们表明，通过增加障碍的半径，自我推进对象的集体运动可以从超扩散到扩散。对于半径较小的障碍物，该系统由沿一个方向移动的大簇组成，对于较大的半径，系统由小簇组成，以不同方向随机移动。
We investigate the influence of obstacles on the collective motion of self propelled objects in the framework of the Vicsek model. The obstacles are arranged in a square lattice and have circular shape. We show that by increasing the radius of the obstacles the collective motion of the self propelled object can be altered from super diffusive to diffusive. For obstacles with small radius, the system is composed of large clusters moving in one direction, for larger radius, the system is composed of small clusters moving randomly in different directions.
