Collective dynamics of trail-interacting particles
Paul Pineau, Samuel Bell, Raphaël Voituriez +1
Trail interactions occur when past particle trajectories bias future motion, rendering the system out of thermodynamic equilibrium. While such systems are abundant in nature, their…

Ordering, spontaneous flows and aging in active fluids depositing tracks
Samuel Bell, Joseph Ackermann, Ananyo Maitra +1
Growing experimental evidence shows that cell monolayers can induce long-lived perturbations to their environment, akin to footprints, which in turn influence the global dynamics o…

Emergence of bidirectional cell laning from collective contact guidance
Mathilde Lacroix, Bart Smeets, Carlès Blanch-Mercader +5
Directed collective cell migration is central in morphogenesis, wound healing and cancer progression1,2. Although it is well-accepted that the molecular anisotropy of the micro-env…
