Clustering and emergent hyperuniformity by breaking microswimmer shape and actuation symmetries

For systems of interfacially driven microswimmers, breaking symmetries of the particle shape and interfacial actuation can lead to self-organization on multiple length scales. For instance, under certain conditions, there is an absorbing phase transition for discoidal swimmers with non-axisymmetric actuation. The particles initially form immotile ordered clusters, and on larger length scales, the clusters realize a spatial distribution characterized by class I disordered hyperuniformity.
