Active Colloids as Tunable Swarmalators — •Veit-Lorenz Heuthe1,2 and Clemens Bechinger1,2 — 1Fachbereich Physik, Universität Konstanz — 2Centre for the Advanced Study of Collective Behaviour, Universität Konstanz
The complexity and functional advantages in various systems from groups of organisms to robotic swarms and digital networks hinge on spatiotemporal patterns arising from the interactions of their constituents. One approach to gain understanding of how these patterns emerge are so-called swarmalators. In this conceptual framework, individual entities exhibit both oscillatory behavior and translational motion, coupled based on their relative phase and position, yielding a diverse array of complex patterns. Here, we introduce a system of active colloids that both oscillate and translate and are coupled to each other in both speed and phase through hydrodynamic interactions. Despite the physical nature of the interactions, the system retains tunability, enabling us to systematically study the behavior of swarmalators in a real system.
