Fluctuation-induced phase separation in metric and topological models of collective motion
David Martin, Hugues Chaté, Cesare Nardini +3
We study the role of noise on the nature of the transition to collective motion in dry active matter. Starting from field theories that predict a continuous transition at the deter…

Freezing a Flock: Motility-Induced Phase Separation in Polar Active Liquids
Geyer Delphine, Martin David, Tailleur Julien +1
Combining model experiments and theory, we investigate the dense phases of polar active matter beyond the conventional flocking picture. We show that above a critical density flock…
