Phase transitions in the collective motions of self-propelled particles are directly impacted both by the initial velocity of each particle, and the repulsive radius surrounding them.
Collective motions of self-propelled particles can be found across many systems in nature. One of the most striking features of this phenomenon is the way in which systems transition between different states of motion: a behavior which can be compared directly with phase transitions in physics. So far, however, it is still not fully understood how these transitions are impacted by the initial parameters of these deeply complex systems.
Through analysis published in The European Physical Journal E, Salma Moushi and colleagues at the University of Hassam II, Morocco, show how the conditions required for transitions to occur are heavily dependent on the initial velocities of each particle, and the repulsion radius surrounding them.
