Anisotropy in the annihilation dynamics of umbilic defects in nematic liquid crystals.
Umbilic defects of strength s = ±1 were induced in a nematic liquid crystal with negative dielectric anisotropy, confined to Hele-Shaw cells with homeotropic boundary conditions, and their annihilation dynamics followed experimentally. The speeds of individual defects of annihilating defect pairs wi...
