“…Considering an homeotropic nematic liquid crystal cell (NLC) with a negative anisotropic dielectric constant, the application of a sufficiently large transverse electric field generates a molecular reorientation on the liquid crystal, resulting in the spontaneous emergence of vortices in the system. Additionally, if one considers a magnetic ring above the cell, the magnetic field structure induce a topological charge in the system, leading to the formation of a vortex triplet 13 with topological charge different fo zero. This vortex triplet is useful to study the dynamics of vortices in nematic liquid crystals.…”

“…These include active motion of topological defects in LC media, [20] decomposition of center and saddle point disclinations, [21,22] ionically charged comet orbit and saddle point disclinations in nematic LCs, [23] skyrmions, [24] motile solitons, [25] and vortex lattices. [26] One example of topological defects, in nematic LCs, is the occurrence of horizontal domains. This was first observed in 1961 by Zvereva and Kapustin then studied in depth by Williams in 1963.…”
