Abstract: Swimming, self-organization, and collective behaviors of active and driven colloids have implications in nature and applications to reconfigurable materials. Here, we focus on swimming or displacement made possible by the complex topologies of defects within nematic liquid crystals (NLCs). In Newtonian fluids, colloidal swimming is challenging; broken symmetries or non-reciprocal forcing are needed to […]
