[EN] We develop it complete mathematical theory for the symmetrical solutions of the generalized nonlinear Schrodinger equation based on the concept of angular pseudomomentum. We consider the symmetric solitons of a ...
[EN] The range of validity of two models for nonlocal nonlinear optics in Nematic Liquid Crystals (NLC) is studied. Particularly the influence of the optical power and the initial position of the beam over its trajectory ...

[EN] We determine the functional behavior near the discrete rotational symmetry axis of discrete vortices of the nonlinear Schrodinger equation. We show that these solutions present a central phase singularity whose charge ...
