Focal Conic Flower Textures at Curved Interfaces
Daniel A. Beller, Mohamed A. Gharbi, Apiradee Honglawan +3
Focal conic domains (FCDs) in smectic-A liquid crystals have drawn much attention both for their exquisitely structured internal form and for their ability to direct the assembly o…
Exploiting imperfections: Directed assembly of surface colloids via bulk topological defects
Marcello Cavallaro, Mohamed A. Gharbi, Daniel A. Beller +6
We exploit the long-ranged elastic fields inherent to confined nematic liquid crystals to assemble colloidal particles trapped at the liquid crystal interface into reconfigurable s…
Ring around the colloid
Marcello Cavallaro, Mohamed A. Gharbi, Daniel A. Beller +6
In this work, we show that Janus washers, genus-one colloids with hybrid anchoring conditions, form topologically required defects in nematic liquid crystals. Experiments under cro…
