Topological defect-propelled swimming of nematic colloids
Tianyi Yao, Žiga Kos, Yimin Luo +3
Non-equilibrium dynamics of topological defects can be used as a fundamental propulsion mechanism in microscopic active matter. Here, we demonstrate swimming of topological defect-…
Tunable colloid trajectories in nematic liquid crystals near wavy walls
Yimin Luo, Daniel A. Beller, Giuseppe Boniello +2
The ability to dictate colloid motion is an important challenge in fields ranging from materials science to living systems. Here, by embedding energy landscapes in confined nematic…
Experimental realization of the "lock-and-key" mechanism in liquid crystals
Yimin Luo, Francesca Serra, Kathleen J. Stebe
The ability to control the movement and assembly of particles in liquid crystals is not only an important route to design functional materials, but also sheds light on the mechanis…
Curvature-driven, One-step Assembly of Reconfigurable Smectic Liquid Crystal "Compound Eye" Lenses
Francesca Serra, Mohamed A. Gharbi, Yimin Luo +5
Confined smectic A liquid crystals (SmA LCs) form topological defects called focal conic domains (FCDs) that focus light as gradient-index lenses. Here, we exploit surface curvatur…
