Delay in the dispersal of flocks moving in unbounded space using long-range interactions

Abstract Since the pioneering work by Vicsek and his collaborators on the motion of self-propelled particles, most of the subsequent studies have focused on the onset of ordered states through a phase transition driven by particle density and noise. Usually, the particles in these systems are placed...
