Shape-controlled orientation and assembly of colloids with sharp edges in nematic liquid crystals
Daniel A. Beller, Mohamed A. Gharbi, Iris B. Liu
The assembly of colloids in nematic liquid crystals via topological defects has been extensively studied for spherical particles, and investigations of other colloid shapes have re…
The Geometry of the Cholesteric Phase
Daniel A. Beller, Thomas Machon, Simon Čopar +4
We propose a construction of a cholesteric pitch axis for an arbitrary nematic director field as an eigenvalue problem. Our definition leads to a Frenet-Serret description of an or…
Elasticity-Dependent Self-assembly of Micro-Templated Chromonic Liquid Crystal Films
Matthew A. Lohr, Marcello Cavallaro, Daniel A. Beller +4
We explore micropatterned director structures of aqueous lyotropic chromonic liquid crystal (LCLC) films created on square lattice cylindrical-micropost substrates. The structures…
