Conditions for the propulsion of a colloid surrounded by a mesoscale phase separation

Autor: Jeanne Decayeux, Marie Jardat, Pierre Illien, Vincent Dahirel

We study a two-dimensional model of an active isotropic colloid whose propulsion is linked to the interactions between solute particles of the bath. The colloid catalyzes a chemical reaction in its vicinity, that yields a local phase separation of so
