我们研究限于二维流形的旋转马达的集合。这些系统表现出不平凡的集体行为，因为旋转运动导致了马达之间的排斥流体动力相互作用。而对于高转速的马达可能表现出结晶有序，它们在低速时形成无序相，其中扩散因速度波动而增强。对于外场驱动的马达和嵌入到粘弹性溶剂中的脂膜中的偶极生物马达，这些效应应该是实验上可以观察到的。
We study collections of rotatory motors confined to two-dimensional manifolds. These systems show a nontrivial collective behavior since the rotational motion leads to a repulsive hydrodynamic interaction between motors. While for high rotation speed motors might exhibit crystalline order, they form at low speed a disordered phase where diffusion is enhanced by velocity fluctuations. These effects should be experimentally observable for motors driven by external fields and for dipolar biological motors embedded into lipid membranes in a viscoelastic solvent.
