Spontaneously ordered motion of self-propelled particles
We study a biologically inspired, inherently non-equilibrium model consisting of self-propelled particles. In the model, particles move on a plane with a velocity of constant magnitude; they locally interact with their neighbours by choosing at each timestep a velocity direction equal to the average direction of their neighbours. Thus, in the limit of vanishing velocities the model becomes anal...
متن کاملMeandering Motion of Self-propelled Particles
A meander is observed in collective motion of some kinds of organisms, for exmaple, a school of fishes and a flight of bats. It is interesting problem to explore why such a motion emerges. In order to investigate the dynamics of organisms, we adopt a two dimensional optimal velocity model, which has been proposed as a dynamical model for the pedestrian flow. Some features in the pedestrian flow...
متن کاملStabilization of Collective Motion of Self-Propelled Particles
This paper presents analysis and design of feedback control laws for stabilization of parallel and circular trajectories of a network of self-propelled particles. Timescale separation of inter-particle alignment and spacing controls permits application of previous convergence results for oscillator phase synchronization and particle motion.
متن کاملCollective motion of rod-shaped self-propelled particles through collision
Self-propelled rods, which propel by themselves in the direction from the tail to the head and align nematically through collision, have been well-investigated theoretically. Various phenomena including true long-range ordered phase with the Giant number fluctuations, and the collective motion composed of many vorices were predicted using the minimal mathematical models of self-propelled rods. ...
متن کاملCollective motion of self-propelled particles interacting without cohesion.
We present a comprehensive study of Vicsek-style self-propelled particle models in two and three space dimensions. The onset of collective motion in such stochastic models with only local alignment interactions is studied in detail and shown to be discontinuous (first-order-like). The properties of the ordered, collectively moving phase are investigated. In a large domain of parameter space inc...
