(contribution withdrawn) Emergence of coherent motion in flocks of deterministics walkers: a coupled maps evolving network perspective — Garcia Cantu Ros Anselmo¹, Basios Vasileos², and •Antonopoulos Christos² — ¹Potstdam Institute for Climate Impact Research PIK, Potsdam, Germany — ²Free University of Brussels ULB, Brussels, Belgium

The emergence of coherence in collective motion described by a system of interacting motiles is analyzed. By means of a nonlinear adaptative coupling, the system elements are able to swing along the route to chaos. Thereby, each motile can display different types of behavior, i.e. from ordered to fully erratic motion, accordingly with its surrounding conditions. The appearance of patterns of collective motion is shown to be related to the emergence of interparticle synchronization and the degree of coherence of motion is quantified by means of a network representation. It is shown that the highest degree of coherence of motion is attained when the system self-drives towards the border between order and chaos. The effect of both particles' density and of considering different weights for the interparticle distances is explored.
