Multistable nematic liquid crystal pores as reconfigurable optical vortex metasurfaces
Claire Doré, Brian Edwards, Nader Engheta +1
Nematic liquid crystals confined in cylindrical pores adopt multiple stable director topologies --- radial, escaped, and arches --- each imprinting a distinct optical signature on…

A sweeping twist defect as a topological flagellum that drives colloid motion
Qi Xing Zhang, Claire Dore, Mojtaba Rajabi +2
Nematic liquid crystals can dramatically reconfigure under dynamic forcing, providing exciting opportunities in active matter. Here, we study a hybrid disk colloid rotated by an ex…
