Event details
Dry and wet layers on a wall are the surface manifestation of equilibrium liquid-vapour phase transitions. Active liquids are disordered nonequilibrium systems that dissipate energy locally, able to produce phase separation in the absence of attractive interactions. We connect the emergent motility-induced separation of model active liquids with effective many-body cohesive interactions, focusing on the paradigmatic case of active Brownian particles [1]. Building on this link, we show how tuneable repulsive barriers allow us to explore various wetting behaviours in two and three-dimensional active matter, with implications on the viable strategies to confine active fluids [2].
