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…
Breaking the Rules for Topological Defects: Smectic Order on Conical Substrates
Ricardo A. Mosna, Daniel A. Beller, Randall D. Kamien
Ordered phases on curved substrates experience a complex interplay of ordering and intrinsic curvature, commonly producing frustration and singularities. This is an especially impo…
The Power of Poincaré: Elucidating the Hidden Symmetries in Focal Conic Domains
Gareth P. Alexander, Bryan Gin-ge Chen, Elisabetta A. Matsumoto +1
Focal conic domains are typically the "smoking gun" by which smectic liquid crystalline phases are identified. The geometry of the equally-spaced smectic layers is highly generic b…
Helical Packings and Phase Transformations of Soft Spheres in Cylinders
Matthew A. Lohr, Ahmed M. Alsayed, Bryan G. Chen +3
The phase behavior of helical packings of thermoresponsive microspheres inside glass capillaries is studied as a function of volume fraction. Stable packings with long-range orient…
