Self-propelled hard disks: implicit alignment and transition to collective motion
We formulate a model of self-propelled hard disks whose dynamics is governed by mutually coupled vectors for velocity and body orientation. Numerical integration at low densities reveals that the expected transition from isotropic to aligned collective motion is present. However, the transition at the Landau meanfield level is strongly first-order, while it is continuous in the Vicsek model. We...
متن کاملNonequilibrium glassy dynamics of self-propelled hard disks.
We analyze the collective dynamics of self-propelled particles in the large-density regime where passive particles undergo a kinetic arrest to an amorphous glassy state. We capture the competition between self-propulsion and crowding effects using a two-dimensional model of self-propelled hard disks, which we study using Monte Carlo simulations. Although the activity drives the system far from ...
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 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 Self-Propelled Particles: Kinetic Phase Transition in One Dimension
We demonstrate that a system of self-propelled particles exhibits spontaneous symmetry breaking and self-organization in one dimension, in contrast with previous analytical predictions. To explain this surprising result we derive a new continuum theory that can account for the development of the symmetry broken state and belongs to the same universality class as the discrete self-propelled part...
