Active particle condensation by non-reciprocal and time-delayed interactions

摘要: We consider the flocking of self-propelling agents in two dimensions, each which communicates with its neighbors within a limited vision-cone. Also, communication occurs some time-delay. The among are modeled by Vicsek rules. In this study we explore combined effect non-reciprocal interaction (induced vision-cone) and presence delay interactions on dynamical pattern formation flock. find that under these influences, without any position-based attractive or confining boundaries, can spontaneously condense into “drops”. Though motion drop, drop as whole is pinned space. novel state flock has well-defined order it stabilized noise present system.
