Activity-driven emulsification of phase-separating binary mixture Diaz, Javier Pagonabarraga Mora, Ignacio Emulsions Moviment brownià Emulsions Brownian movements Active particles self-assemble into emergent structures that respond sensitively to external constraints. Consequently, their behavior under confinement is complex, especially in soft confined media, leading to diverse emergent morphologies. Through computer simulations, we investigate the dynamical interplay between active Brownian particles and a binary mixture. Our results show that active particles stabilize nonequilibrium morphologies, arresting coarsening by exerting active pressure that competes with surface tension. For moderate activities, particles stabilize an active emulsion with a well-defined droplet size. At higher activities, when particles can cross the liquid domains, a dynamic emulsion with large droplet dispersion is sustained. Furthermore, active particles drive phase-separated mixtures away from equilibrium configurations, demonstrating a rich coassembly behavior due to competing energy scales in the system. 2026-03-25T15:29:17Z 2026-03-25T15:29:17Z 2025-03-07 2026-03-25T15:29:17Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion 0031-9007 https://hdl.handle.net/2445/228507 766992 eng Reproducció del document publicat a: https://doi.org/10.1103/PhysRevLett.134.098301 Physical Review Letters, 2025, vol. 134, p. 1-6 https://doi.org/10.1103/PhysRevLett.134.098301 (c) American Physical Society, 2025 info:eu-repo/semantics/openAccess 6 p. application/pdf American Physical Society Articles publicats en revistes (Física de la Matèria Condensada)
