A diffuse-interface theory of active nematic interfaces: transport mechanisms and modal structure
Rodrigo C. V. Coelho, Mykola Tasinkevych, Margarida M. Telo da Gama
We develop a long-wavelength theory for the linear stability of a flat interface between an active nematic and an isotropic fluid. Starting from a diffuse-interface Cahn--Hilliard-…

Phase Separation in Mixtures of Nematic and Isotropic Fluids
Margarida M. Telo da Gama, Rodrigo C. V. Coelho
Mixtures of nematic liquid crystals and isotropic fluids display a diverse range of phase behaviors, arising from the coupling between orientational order and concentration fluctua…

Liquid crystal torons in Poiseuille-like flows
Guilherme N. C. Amaral, Hanqing Zhao, Mahmoud Sedahmed +5
Three-dimensional (3D) simulations of the structure of liquid crystal (LC) torons, topologically protected distortions of the LC director field, under material flows are rare but e…
