We propose a simple experimental scheme to generate spin textures in the ground state of interacting ultracold bosonic atoms loaded in a two-dimensional harmonic trap. Our scheme is based on two copropagating Laguerre-Gauss laser beams illuminating the atoms and coupling two of their internal ground...
