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…
Singular Values, Nematic Disclinations, and Emergent Biaxiality
Simon Čopar, Mark R. Dennis, Randall D. Kamien +1
Both uniaxial and biaxial nematic liquid crystals are defined by orientational ordering of their building blocks. While uniaxial nematics only orient the long molecular axis, biaxi…
