Point defects in 2-D liquid crystals with singular potential: profiles and stability

Zhiyuan Geng, Wei Wang

We study radial symmetric point defects with degree $\frac{k}{2}$ in 2D disk or $R^{2}$ in $Q$ -tensor framework with singular bulk energy, which is defined by Bingham closu…

Regularity of Minimizers of a Tensor-valued Variational Obstacle Problem in Three Dimensions

Zhiyuan Geng, Jiajun Tong

Motivated by Ball and Majumdar's modification of Landau-de Gennes model for nematic liquid crystals, we study energy-minimizer $Q$ of a tensor-valued variational obstacle problem i…
