Theory of hybrid defects, with coupled orientational order parameters, on flat and curved surfaces
Lincoln Paik, Jonathan V. Selinger
Many physical systems involve two types of orientational order, which are coupled together. For example, ferroelectric nematic liquid crystals have coupled polar and nematic order,…

Spontaneous Cholesteric Phase in Ferroelectric Nematic Liquid Crystals: Preference for Integer Number of Pitches
Lincoln Paik, Jonathan V. Selinger
In a ferroelectric nematic liquid crystal, the electrostatic interaction can induce a spontaneous cholesteric helix, even if the material is not chiral. If the liquid-crystal cell…

Flexoelectricity versus Electrostatics in Polar Nematic Liquid Crystals
Lincoln Paik, Jonathan V. Selinger
Polar nematic liquid crystals have two special features, compared with conventional nematic liquid crystals. First, because of flexoelectricity, the combination of polar order and…
