Kink soliton dynamics for systems incorporating higher-order nonlinearity and dispersion

Abstract: We investigate the dynamic behavior of kink solitons in systems with quintic order nonlinear interaction and higher-order dispersion effects. Based on the nonlinear Schrödinger equation model incorporating higher-order dispersion and higher-order nonlinear interaction, we derive the analytical kink soliton solution of such system model based on the F-expansion method. We show the unique kink soliton features by the analytical formulation and typical graphic illustration. The theoretical results presented in this study can be used to guide the experimental observation of kink solitons in systems with higher-order dispersion and higher-order nonlinear interaction.
