Abstract: C1.00222 : Intermittency and ergodicity breaking in a system of interacting self-propelled particles
Author:
A comprehensive dynamical model for cooperative motion of
self-propelled particles [Dossetti et al. Phys. Rev. E 79, 051115
(2009)], that combines velocity alignment interactions, spatial
interactions, and angular noise, is studied. The noise considered
in this model comes about nonlinear with correlations that decay
in time, leading to a unique collective behavior. In particular,
for a certain arrangement of the parameters, the system develops
intermittent behavior and some sort of ergodicity breaking. In
this work, we characterize these phenomena by studying the
distributions of time intervals between turbulent bursts and
changes between metastable states, respectively.
