Solitary wave, breather wave and rogue wave solutions of an inhomogeneous fifth-order nonlinear Schrödinger equation from Heisenberg ferromagnetism. (English) Zbl 1412.35306
Summary: In this paper, we consider an inhomogeneous fifth-order nonlinear Schrodinger equation from Heisenberg ferromagnetism, which describes the dynamics of a site-dependent Heisenberg ferromagnetic spin chain. Based on its Lax pair, we study the determinant representation of the \(n\)-fold Darboux transformation (DT). Furthermore, by using the \(n\)-fold DT, we obtain the higher-order solitary wave, breather wave and rogue wave solutions of the equation, respectively. Finally, the dynamic characteristics of these exact solutions are discussed.
