Underlying virtually any biological function is the organization of proteins and other molecules in time and space. A current challenge in statistical physics is to uncover universal principles governing the self-organization of macromolecules in crowded environments and driven away from equilibrium. Usually, Ostwald ripening leads to the macroscopic phase separation. In contrast, aggregates of proteins in living cells typically show "size control" and are stable over an extended time without coarsening, which can be rationalized in terms of reverse Ostwald ripening. We study a thermodynamically consistent, chemically driven two component reaction-diffusion system in which particles of one species attract each other. Combining insights from stochastic thermodynamics and active field theories, we aim to understand how phase coexistence is modified by the chemical activity.
