By contrast, it is largely unclear how the interplay between cell shape and self-propulsion controls the meso- and macroscale behavior of active matter. Here, we analyze large-scale simulations of homo- and heterogeneous self-propelled particle systems to identify generic effects of broken particle symmetry on collective motion. We find that even small violations of fore-aft symmetry lead to fundamentally different collective behaviors, which may facilitate dem","authors_text":"H. H. Wensink, J. Dunkel, R. E. Goldstein, V.
