Universal Scaling Laws for a Generic Swimmer Model
Bruno Ventéjou, Thibaut Métivet, Aurélie Dupont +1
We have developed a minimal model of a swimmer without body deformation based on force and torque dipoles which allows accurate 3D Navier-Stokes calculations. Our model can reprodu…

Condensation and Synchronization in Aligning Chiral Active Matter
Yujia Wang, Bruno Ventéjou, Hugues Chaté +1
We show that spontaneous density segregation in dense systems of aligning circle swimmers is a condensation phenomenon at odds with the phase separation scenarios usually observed…

Behavioral transition of a fish school in a crowded environment
Bruno Ventéjou, Iris Magniez--Papillon, Eric Bertin +2
In open water, social fish gather to form schools, in which fish generally align with each other. In this work, we study how this social behavior evolves when perturbed by artifici…
