We study discrete solitons (kinks) accessible in state-of-the-art trapped ion experiments [1], considering zigzag crystals and quasi-3D configurations, both theoretically and experimentally[2]. We extend the theoretical understanding of different phenomena predicted and recently experimentally observed in the structure and dynamics of these topological excitations. Employing tools from topological degree theory, we analyze bifurcations of crystal configurations in dependence on the trapping parameters, and investigate the formation of kink configurations and the transformations of kinks between different structures. We present configurations of pairs of interacting kinks stable for long times, offering the perspective for exploring and exploiting complex collective nonlinear excitations, controllable on the quantum level.
