Out of equilibrium stationary states, percolation, and sub-critical instabilities in a fully non conservative system
Mathieu Génois, Pascal Hersen, Eric Bertin +2
The exploration of the phase diagram of a minimal model for barchan fields leads to the description of three distinct phases for the system: stationary, percolable and unstable. In…
A note on the duality between interaction responses and mutual positions in flocking and schooling
Andrea Perna, Guillaume Gregoire, Richard P. Mann
Background: Recent research in animal behaviour has contributed to determine how alignment, turning responses, and changes of speed mediate flocking and schooling interactions in d…
When dunes move together, structure of deserts emerges
Mathieu Génois, Pascal Hersen, Sylvain Courrech du Pont +1
Crescent shaped barchan dunes are highly mobile dunes that are usually presented as a prototypical model of sand dunes. Although they have been theoretically shown to be unstable w…
Interface dynamics in shear-banding flow of giant micelles
S. Lerouge, M. A. Fardin, M. Argentina +2
We report on a non trivial dynamics of the interface between shear bands following a start-up of flow in a semi-dilute wormlike micellar system investigated using a combination of…
Collective motion of self-propelled particles interacting without cohesion
Hugues Chaté, Francesco Ginelli, Guillaume Grégoire +1
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 onl…
Comment on ``Phase Transitions in Systems of Self-Propelled Agents and Related Network Models''
Hugues Chaté, Francesco Ginelli, Guillaume Grégoire
In this comment we show that the transition to collective motion in Vicsek-like systems with angular noise remain discontinuous for large velocity values. Thus, the networks studie…
