Abstract

We investigate a vortex triplet induced by the combination of an electric and magnetic field onto a homeotropic nematic liquid crystal cell. The electric and magnetic fields are generated by two parallel electrodes and a magnetic ring, respectively. The vortex triplet remains stable and trapped at the center of the magnetic ring. Based on forcing the Ginzburg-Landau equation, valid close to the re-orientational transition, allow us to establish the origin of the vortex triplet. Numerical simulations show a quite fair agreement with theoretical findings and experimental observations.
