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…
Capillary wave formation in conserved active emulsions
Florian Raßhofer, Simon Bauer, Alexander Ziepke +2
The dynamics of phase-separated interfaces shape the behavior of both passive and active condensates. While surface tension in equilibrium systems minimizes interface length, non-e…
Acoustic signaling enables collective perception and control in active matter systems
Alexander Ziepke, Ivan Maryshev, Igor S. Aranson +1
Emergent cooperative functionality in active matter systems plays a crucial role in various applications of active swarms, ranging from pollutant foraging and collective threat det…
Supramolecular assemblies in active motor-filament systems: micelles, bilayers, and foams
Filippo De Luca, Ivan Maryshev, Erwin Frey
Active matter systems evade the constraints of thermal equilibrium, leading to the emergence of intriguing collective behavior. A paradigmatic example is given by motor-filament mi…
