Directional soliton and breather beams [PDF]
Proceedings of the National Academy of Sciences, 2019 Significance Understanding the fundamental dynamics of directional and localized waves is of significant importance for modeling ocean waves as well as predicting extreme events. We report a theoretical framework, based on the universal (2D + 1) nonlinear Schrödinger equation, that allows the construction of slanted solitons and breathers on ...

Review on the Stability of the Peregrine and Related Breathers
Frontiers in Physics, 2020 In this note, we review stability properties in energy spaces of three important nonlinear Schrödinger breathers: Peregrine, Kuznetsov-Ma, and Akhmediev.

Fano Resonances with Discrete Breathers [PDF]
Physical Review Letters, 2003 A theoretical study of linear wave scattering by time-periodic spatially localized excitations (discrete breathers (DB)) is presented. We obtain that the wave propagation is strongly influenced by a local coupling between an open and closed channels generated by the DB.

Bounded States for Breathers–Soliton and Breathers of Sine–Gordon Equation [PDF]
Nonlinear Dynamics, 2021 Abstract The Wronskians solutions to the sine-Gordon (sG) equation that can provide interaction of different kinds of solutions are revisited. A novel expression N-soliton solution with a nonzero background is presented which is used to construct the soliton and breather solutions.

Numerical modeling of stationary pseudospin waves on a graphene monoatomic films
Discrete and Continuous Models and Applied Computational Science, 2019 For the first time, the theoretical model of the spin-electron structure of a singlelayer graphene film was proposed by Wallace. The literature also describes ferromagnetism generated by none of the three common causes: impurities, defects, boundaries ...

Management of breather interactions
Physical Review Research, 2022 We propose theoretically and confirm experimentally a general approach to manage multiple nonlinear interactions of coherent solitary wave structures on an unstable background–-breathers.

Multiple Soliton Interactions on the Surface of Deep Water
Fluids, 2020 The paper presents the long-time dynamics with multiple collisions of breathers in the super compact Zakharov equation for unidirectional deep water waves. Solutions in the form of breathers were found numerically by the Petviashvili method. In the terms

Scientific ReportsAbstractModulation instability is a phenomenon in which a minor disturbance within a carrier wave gradually amplifies over time, leading to the formation of a series of compressed waves with higher amplitudes. In terms of frequency analysis, this process results in the generation of new frequencies on both sides of the original carrier wave frequency ...
