标题： Large-scale dynamics in visual quorum sensing chiral suspensions

摘要： 活性物质的运动诱导相分离是一种有效的聚集机制，然而生物系统通过组分之间的通信表现出更丰富的组织结构。 我们研究了当其视野锥内的邻近密度超过阈值时会改变手性的活性粒子悬浮液，这是一种基于通信的非互惠相互作用，类似于群体感应。 调整视野锥可以触发可编程的转变：从无序到相分离再到超均匀性。 值得注意的是，相分离会引发大尺度循环，具有坚固的边缘电流，持续围绕密集簇流动，而内部粒子分布则变得有效超均匀。 这些是真实的非互惠效应，即使在没有立体相互作用的情况下也会发生。 值得注意的是，在活性-被动混合物中，仅需5%的群体感应手性粒子即可引发集体循环。 因此，简单的基于感知的规则可以产生类似生命秩序的现象，为可编程活性材料和微机器人集群提供了设计原则。 显示英文摘要

摘要： Motility induced phase separation is an efficient aggregation mechanism of active matter, yet biological systems exhibit richer organization through communication among constituents. We investigate suspensions of active particles that change chirality when neighbor density within their visual cone exceeds a threshold, a communication based non-reciprocal interaction akin to quorum sensing. Tuning the visual cone triggers programmable transitions: from disorder to phase separation to hyper-uniformity. Notably, phase separation triggers large-scale circulation, with robust edge currents persistently flowing around dense clusters, while particle distributions inside become effectively hyper-uniform. These are genuine non-reciprocal effects which occur even in the absence of steric interactions. Remarkably, in active-passive mixtures, only 5% quorum-sensing chiral particles suffice to induce collective circulation. Thus, simple perception-based rules can generate life-like order, offering design principles for programmable active materials and micro-robotic swarms.
