Geometry of Bend: Singular Lines and Defects in Twist-Bend Nematics
Jack Binysh, Joseph Pollard, Gareth P. Alexander
We describe the geometry of bend distortions in twist-bend nematic liquid crystals in terms of their fundamental degeneracies, which we call lines. These represent a new class…

Singular Contact Geometry and Beltrami Fields in Cholesteric Liquid Crystals
Joseph Pollard, Gareth P. Alexander
The description of point defects in chiral liquid crystals via topological methods requires the introduction of singular contact structures, a generalisation of regular contact str…

Point Defects, Chirality and Singularity Theory in Cholesteric Liquid Crystal Droplets
Joseph Pollard, Gregor Posnjak, Gareth P. Alexander +2
We develop a theory of point defects in cholesterics and textures in spherical droplets with normal anchoring. The local structure of chiral defects is described by singularity the…
