The structures were generated numerically for a nonlinear optical medium with competing quadratic and cubic nonlinearities. The atoms which formed the molecule were fully three-dimensional solitons linked through a staircaselike macroscopic phase.Keywords: Color; Perturbation techniques; Robustness (control systems); Angular momentum; Solitons20032015-12-12
