title: Nematicons beyond the perturbative regime.
abstract: We model spatial solitons in nematic liquid crystals, accounting for nonperturbative excitation and related effects, such as power-dependent self steering. We also address the interplay between nonlocality and saturation typical of a reorientational medium.
