Computing with non-orientable defects: nematics, smectics and natural patterns
Chiqun Zhang, Amit Acharya, Alan C. Newell +1
Defects are a ubiquitous feature of ordered media. They have certain universal features, independent of the underlying physical system, reflecting their topological origins. While…

Computational modeling of tactoid dynamics in chromonic liquid crystals
Chiqun Zhang, Amit Acharya, Noel J. Walkington +1
Motivated by recent experiments, the isotropic-nematic phase transition in chromonic liquid crystals is studied. As temperature decreases, nematic nuclei nucleate, grow, and coales…

A non-traditional view on the modeling of nematic disclination dynamics
Chiqun Zhang, Xiaohan Zhang, Amit Acharya +2
Nonsingular disclination dynamics in a uniaxial nematic liquid crystal is modeled within a mathematical framework where the kinematics is a direct extension of the classical way of…
