“…In this work, we focus on the impact of initial states on the emergent behaviors in an active system of self-propelled particles based on a model we developed previously. [28] In this model, an active reorientation rule is incorporated for particles at collisions, to mimic the collision avoidance behavior commonly adopted in cell colonies, [29,30] animal herds, [31,32] swarming robots, [33] and traffic flows. [34] The coupling between self-propulsion and active reorientation produces richer dynamics compared with previous models merely involving translation or rotation.…”

There are rich emergent phase behaviors in non-equilibrium active systems. Flocking and clustering are two representative dynamic phases. The relationship between these two phases is still unclear. In the paper, we numerically investigate the evolution of flocking and clustering in a system consisting of selfpropelled particles with active reorientation. We consider the interplay between flocking and clustering phases with different initial configurations, and observe a domain in steady state order parameter phase diagrams sensitive to the choice of initial configurations. Specifically, by tuning the initial degree of polar ordering, either a more ordered flocking or a disordered clustering state can be observed in the steady state. These results enlighten us to manipulate emergent behaviors and collective motions of active system, and are qualitatively different from the emergence of a new bi-stable regime observed in aligned active particles due to an explicit attraction [Großmann R, Schimansky-Geier L and Romanczuk P 2012 New J. Phys. 14 073033].
