Abstract

Two-dimensional axisymmetric propagating single solitons are generated experimentally in a radial Poiseuille flow of homeotropic nematic liquid crystals. In different pressure gradient regimes two types of single solitons are excited and identified. Interference patterns of transmitted light through crossed polarizers are photographed. Distributions of the director corresponding to these solitons are discussed.
