Chiral structures and defects of lyotropic chromonic liquid crystals induced by saddle-splay elasticity
Zoey S. Davidson, Louis Kang, Joonwoo Jeong +4
An experimental and theoretical study of lyotropic chromonic liquid crystals (LCLCs) confined in cylinders with degenerate planar boundary conditions elucidates LCLC director confi…
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…
The 2-modular permutation modules on fixed point free involutions of symmetric groups
Peter Collings
We enumerate over even characteristic the components of the permutation module of the symmetric group of even degree acting on the set of its fixed point free involutions. We find…
Fixed point sets for permutation modules
Peter Collings
We investigate the representation of the symmetric group afforded by the action on its conjugacy class of fixed point free involutions, over an algebraically closed field of finite…
Effective index of refraction, optical rotation, and circular dichroism in isotropic chiral liquid crystals
D. Lacoste, P. J. Collings, T. C. Lubensky
This paper concerns optical properties of the isotropic phase above the isotropic-cholesteric transition and of the blue phase BP III. We introduce an effective index, which descri…
Field-Dependent Tilt and Birefringence of Electroclinic Liquid Crystals: Theory and Experiment
J. V. Selinger, P. J. Collings, R. Shashidhar
An unresolved issue in the theory of liquid crystals is the molecular basis of the electroclinic effect in the smectic-A phase. Recent x-ray scattering experiments suggest that, in…
