Phase separation of macromolecules has recently attracted substantial interest, in particular in the context of membrane-less organelles in the cell. These organelles are typically modeled as condensates. Instead of coarsening to a fully phase separated state, such protein condensates form stable droplets of finite size in vivo. Therefore, an important question is the role of non-equilibrium processes since the physical processes underlying stable droplet behavior are not yet resolved. Here we study active model B+, a scalar field theory developed in the context of motile active matter, and employ methods of active liquid theory to explore activity as the underlying mechanism for condensate stabilization.
