| Abstract: | A method was proposed to visualize collective displacements of particles in diffusion motion in liquids. Using this method, in molecular dynamics models of liquid argon, groups of collectively moving atoms were detected, which had the shape of long curved flows, often appearing as vortex-like structures. These structures are revealed only by considering movements of atoms over long time intervals, on the order of tens and hundreds of picoseconds, and over long distances, on the order of tens of nanometers. |
