Hydrodynamic coarsening of bubbles in a dense liquid: A molecular dynamics perspective

We investigate the kinetics of bubble coarsening in a single-component Lennard-Jones fluid using large-scale molecular dynamics simulations. A homogeneous high-temperature system is quenched below the vapor-liquid critical temperature to induce nucleation and growth of vapor bubb...

Activity removes transport arrest and restores phase separation under geometric confinement

Transport and phase separation under geometric confinement play a central role in systems ranging from intracellular organization to porous materials, yet how nonequilibrium activity reshapes collective ordering in constrained environments remains unresolved. Here we demonstrate...
