Nonlinear tunneling effect of snakelike self-similar waves in a grating dual-core waveguide amplifier

open access: yesResults in Physics, 2019
We study on the nonlinear tunneling effect of snakelike self-similar waves of the nonlinear Schrödinger equation with gains in an asymmetric dual-core waveguide amplifier with a long-period grating.

Hylomorphic solitons on lattices

open access: yes, 2010
This paper is devoted to prove the existence of solitons on lattices. We are interested in solitary waves and solitons whose existence is related to the ratio energy/charge. These solitary waves are called hylomorphic.

Wave-unlocking transition in resonantly coupled complex Ginzburg-Landau equations [PDF]

open access: yes, 1996
We study the effect of spatial frequency-forcing on standing-wave solutions of coupled complex Ginzburg-Landau equations. The model considered describes several situations of nonlinear counterpropagating waves and also of the dynamics of polarized light ...

Instability of Ion Cyclotron Waves (ICWS) at the Expense of Lower Hybrid Drift Waves (LHDWS) Turbulence Energy

open access: yesEast European Journal of Physics, 2023
Instability of ion cyclotron waves(ICWs) is investigated in presence of lower hybrid drift waves(LHDWs) turbulence. Plasma inhomogeneity in the Earth’s magnetopause region supports a range of low frequency drift wave turbulent fields due to gradients in

Instability of two interacting, quasi-monochromatic waves in shallow water

open access: yes, 2002
We study the nonlinear interactions of waves with a doubled-peaked power spectrum in shallow water. The starting point is the prototypical equation for nonlinear uni-directional waves in shallow water, i.e. the Korteweg de Vries equation.

Rogue Waves: From Nonlinear Schrödinger Breather Solutions to Sea-Keeping Test [PDF]

open access: yes, 2013
Under suitable assumptions, the nonlinear dynamics of surface gravity waves can be modeled by the one-dimensional nonlinear Schrödinger equation. Besides traveling wave solutions like solitons, this model admits also breather solutions that are now ...

Analysis of Magnetic Fields in Inertial Alfven Wave Collisions

open access: yes, 2014
Turbulence in astrophysical and space plasmas is dominated by the nonlinear interaction of counterpropagating Alfven waves. Most Alfven wave turbulence theories have been based on ideal plasma models, such as incompressible MHD, for Alfven waves at large

Modelling nonlinear hydroelastic waves [PDF]

open access: yesPhilosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2011
This paper uses the special Cosserat theory of hyperelastic shells satisfying Kirchoff’s hypothesis and irrotational flow theory to model the interaction between a heavy thin elastic sheet and an infinite ocean beneath it. From a general discussion of three-dimensional motions, involving an Eulerian description of the flow and a Lagrangian description ...
