Nematic Liquid Crystal Locking Menisci

Nematic Liquid Crystal Locking Menisci

We study meniscus driven locking of point defects of nematic liquid crystals confined within a cylindrical tube with free ends. Curvilinear coordinate system is introduced in order to focus on the phenomena of both (convex and concave) types of menisci. Frank's description in terms of the nemat...
