Journal ArticleDOI
General high-order rogue waves and their dynamics in the nonlinear Schrödinger equation
Yasuhiro Ohta,Jianke Yang +1 more
TL;DR: Akhmediev et al. as mentioned in this paper derived general high-order rogue waves in the nonlinear Schrodinger equation using the bilinear method and showed that the general N − 1 free irreducible complex parameters have the highest peak amplitudes among all rogue waves of the same order.
Journal ArticleDOI
Rogue waves in the Davey-Stewartson I equation.
Yasuhiro Ohta,Jianke Yang +1 more
TL;DR: General rogue waves in the Davey-Stewartson-I equation are derived by the bilinear method and it is shown that the simplest (fundamental) rogue waves are line rogue waves which arise from the constant background with a line profile and then disappear into the constant Background.
Journal ArticleDOI
Dynamics of rogue waves in the Davey–Stewartson II equation
Yasuhiro Ohta,Jianke Yang +1 more
TL;DR: In this article, it was shown that the simplest (fundamental) rogue waves are line rogue waves which arise from the constant background in a line profile and then retreat back to the background again.
Journal ArticleDOI
General N-Dark–Dark Solitons in the Coupled Nonlinear Schrödinger Equations
TL;DR: In this article, the authors derived n-dark-dark solitons in the integrable coupled NLS equations by the KP-hierarchy reduction method, and they showed that these non-linearities exist when nonlinearities are all defocusing, or both focusing and defocusing non linearities are mixed.
Journal ArticleDOI
Sasa-Satsuma higher-order nonlinear Schrödinger equation and its bilinearization and multisoliton solutions.
TL;DR: The correct bilinearization is given based on the interpretation of the Sasa-Satsuma equation as a reduction of the three-component Kadomtsev-Petviashvili hierarchy and multisoliton formulas are obtained.
