Colloidal spinners self-organize into an odd crystalline whorl state

ORAL

Abstract

We report the assembly of an odd crystal comprised of thousands of spinning colloidal magnets. By activating the system at the single unit level, we extend the simple longitudinal interactions of typical crystals to incorporate a broader class of transverse interactions. At the system scale, this deceptively simple generalization organizes colloidal spinners into a crystalline whorl state that blurs the line between solid and liquid. The crystal whorl dynamics drive super-diffusive mass transport, which can be controlled over orders of magnitude. We show this state is generically accessible due to an instability driven by odd elastic stresses.
