论文摘要
控制主动物质的运动是一个核心问题，最近在从非平衡物理学到化学工程和生物学的领域中引起了极大的关注。已经开发了用于控制主动物质的不同方法，并且与旋转对称性破裂（手性）对有限的空间和活动物质的物理限制是两个突出的机制。但是，需要更好地理解由于物理限制引起的模式形成与手性运动的顺序之间的相互作用。在这项研究中，我们在圆形边界限制下对手性自行颗粒进行数值模拟。受限制的自旋细胞的集体运动可以取决于其手性，使其截然不同。粒子相互作用和边界壁之间方向变化的平衡对于产生有序的集体运动至关重要。我们的结果阐明了空间边界效应在控制手性活动物质中的作用。
Controlling the motion of active matter is a central issue that has recently garnered significant attention in fields ranging from non-equilibrium physics to chemical engineering and biology. Distinct methods for controlling active matter have been developed, and physical confinement to limited space and active matter with broken rotational symmetry (chirality) are two prominent mechanisms. However, the interplay between pattern formation due to physical constraints and the ordering by chiral motion needs to be better understood. In this study, we conduct numerical simulations of chiral self-propelled particles under circular boundary confinement. The collective motion of confined self-propelled particles can take drastically different forms depending on their chirality. The balance of orientation changes between particle interaction and the boundary wall is essential for generating ordered collective motion. Our results clarify the role of the steric boundary effect in controlling chiral active matter.
