Vector gap solitons in pseudo-Zeeman lattices

Soliton complexes provide an effective way to study the interaction of solitons and the dynamics of nonlinear systems. Based on the realization of pseudo-Zeeman lattice in optics, the soliton components of the soliton complexes have different potential fields, and thus have different propagation characteristics. The interaction of the soliton components makes the soliton complexes exhibit novel and unique propagation characteristics, that is, passing through the lattice without reflection and the weak light controlling the strong light through the attraction between the components of the soliton complexes
