|Title:||Rotational interaction of topological defects in planar nematic liquid crystals.|
|Author:||Vromans, Arthur Johannes|
|Abstract:||A recent paper [DeCamp et al 2015] reported dynamical effects of defect orientation in experiments with planar nematic liquid crystals. The numerical determination of defect orientations was complicated by the absence of a rigorous definition of defect orientation in the paper. In this thesis I will introduce rigorously a defect orientation which can be easily determined numerically. I will show that defect orientation is a significant factor in the dynamics of defect annihilations with most notably an orthogonal velocity component not documented in the literature.|
