Although spiraling of two nematicons was demonstrated earlier [2], the dynamics of optical beams carrying phase singularities in nematics were never explored before.Keywords: Charge flipping; Nematicons; Nematics; Nonlocal; Optical beams; Phase singularities; Spatial solitons; Theoretical prediction; Vortex solitons; Crystals; Electron optics; Liquid lasers; Optics; Quantum electronics; Solitons; Vortex flow; Nematic liquid cr201110.1109/CLEOE.2011.59426982016-02-24
