Active Model B from Mass-Conserving Reaction-Diffusion Systems
Davide Toffenetti, Beatrice Nettuno, Henrik Weyer +1
We show that the late-time dynamics of a minimal three-component mass-conserving reaction--diffusion system reduce to a scalar active field theory, Active Model B (AMB), in…

Non-equilibrium phase coexistence in conserved chemically active mixtures
Florian Raßhofer, Erwin Frey
Chemical activity is known to affect phase coexistence and coarsening in liquid mixtures, most commonly through reaction-induced changes of intermolecular interactions. Here, we an…

Local composition controls pattern formation in conserved active emulsions
Florian Raßhofer, Erwin Frey
Phase separation in passive systems leads to uncontrolled droplet growth, limiting structural control in soft materials and cells. We identify a generic mechanism to arrest coarsen…
