论文摘要
可以从超出直接微观粒子相互作用的统计力的平衡中理解许多颗粒的悬浮液中的大规模集体行为。在这里，我们回顾了可以在自prop的活性布朗颗粒的悬浮液中产生的集体力量的某些方面：隔离下的壁力，界面力和力在悬浮液介导的浸入物体上。即使对于非对准的活性颗粒，这些力也与壁和物体引起的粒子方向的不均匀极化密切相关，或者是不均匀的密度曲线。最后，我们指出了未来的方向和有前途的领域，用于在合成活动中应用集体力量以及它们在活跃物质中的作用。
Large-scale collective behavior in suspensions of many particles can be understood from the balance of statistical forces emerging beyond the direct microscopic particle interactions. Here we review some aspects of the collective forces that can arise in suspensions of self-propelled active Brownian particles: wall forces under confinement, interfacial forces, and forces on immersed bodies mediated by the suspension. Even for non-aligning active particles, these forces are intimately related to a non-uniform polarization of particle orientations induced by walls and bodies, or inhomogeneous density profiles. We conclude by pointing out future directions and promising areas for the application of collective forces in synthetic active matter, as well as their role in living active matter.
