Abstract:In this paper, nonlinear dynamics of higher-order rogue waves are investigated for a fifthorder nonlinear Schrödinger equation, which can be used to depict the Heisenberg ferromagnetic spin chain. A generalized Darboux transformation is constructed based on the Lax pair. Higher-order rogue waves solutions are given in terms of a recursive formula. Using numerical simulation, the first-order to the thirdorder rogue waves are displayed on the basis of some free parameters, which play a crucial role in affecting … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
