非互易和时滞相互作用下的活性粒子凝聚
Active Particle Condensation by Nonreciprocal and Time-delayed Interactions
摘要：
我们考虑群集的自推进剂在两个维度，其中每个与它的邻居在有限的视觉锥。此外，通信发生一定的延迟。代理之间的通信采用Vicsek规则建模。在这项研究中，我们探讨了代理之间的非互惠互动，诱导他们的视锥，以及延迟的相互作用的动态斑图形成内的羊群。我们发现，在这两种影响下，没有任何基于位置的吸引相互作用或限制边界，代理可以自发地凝聚成滴。虽然代理人是在运动的下降，下降作为一个整体，实际上是钉在空间。我们还发现，这种新的状态的羊群有一个明确的秩序稳定的噪声存在于系统中。
英文摘要：
We consider flocking of self-propelling agents in two dimensions, each of which communicates with its neighbors within a limited vision cone. Also, the communication occurs with some delay. The communication among the agents are modeled by Vicsek rules. In this study we explore the effect of non-reciprocal interaction among the agents, induced by their vision cone, together with the delayed interactions on the dynamical pattern formation within the flock. We find that under these two influences and without any position based attractive interactions or confining boundaries, the agents can spontaneously condense into drops. Though the agents are in motion within the drop, the drop as whole is virtually pinned in space. We also find that this novel state of the flock has a well defined order stabilized by the noise present in the system.
