DESCRIPTION:Repulsive interactions govern the dynamics of matter from atoms to animals. Using theory\, simulations\, and experiments\, we find that an ensemble of repulsive particles spreads compactly with a sharp boundary\, in contrast to the diffusive spreading of Brownian particles. Starting from the pair interactions\, at high densities\, the many-body dynamics follow nonlinear diffusion with a self-similar expansion. We give theoretical predictions that we verify experimentally and numerically for the scaling of the dynamics for various forms of potentials. When the interactions are long-ranged\, the system retains a long-lived memory of the original pattern. We demonstrate that below a threshold\, the initial distribution seeds the resulting pattern\, encoding the future structure of an unconfined and dynamically evolving system.\n\nTitle: MPI-DS Seminar: Compact expansion of a repulsive suspension\nSpeaker: Naomi Oppenheimer\nOrganizer: Max-Planck-Institut für Dynamik und Selbstorganisation\nHost: MPI-DS\nContact: Eberhard Bodenschatz\, eberhard.bodenschatz@ds.mpg.de\n
