Korteweg-de Vries description of Helmholtz-Kerr dark solitons [PDF]

, 2006
A wide variety of different physical systems can be described by a relatively small set of universal equations. For example, small-amplitude nonlinear Schrödinger dark solitons can be described by a Korteweg-de Vries (KdV) equation.

Interactions of large amplitude solitary waves in viscous fluid conduits [PDF]

, 2014
The free interface separating an exterior, viscous fluid from an intrusive conduit of buoyant, less viscous fluid is known to support strongly nonlinear solitary waves due to a balance between viscosity-induced dispersion and buoyancy-induced ...

On the modulation instability development in optical fiber systems

, 2010
Extensive numerical simulations were performed to investigate all stages of modulation instability development from the initial pulse of pico-second duration in photonic crystal fiber: quasi-solitons and dispersive waves formation, their interaction ...

Numerical Simulation of Highly Dispersive Dark Optical Solitons with Kerr Law of Nonlinear Refractive Index by Laplace–Adomian Decomposition Method

Proceedings of the Bulgarian Academy of Sciences, 2023
This work is a numerical perspective to highly dispersive dark optical solitons by using Laplace-Adomian decomposition method. The results are reported using this scheme with highly precise accuracy and the error measure is stunningly low.

Time-Reversal of Nonlinear Waves - Applicability and Limitations [PDF]

, 2016
Time-reversal (TR) refocusing of waves is one of fundamental principles in wave physics. Using the TR approach, "Time-reversal mirrors" can physically create a time-reversed wave that exactly refocus back, in space and time, to its original source ...

Internal modes of oscillations of topological solitons in highly dispersive media

Scientific Herald of Uzhhorod University.Series Physics, 2005
Точно розв’язано проблему стійкості і спектру лінійних збуджень солітона (кінка) для дисперсійного рівняння синус-Гордон та 4-моделі. Показано, що повний спектр коливань солітона складається з дискретного набору частот внутрішніх мод і однозонного суцільного хвильового спектру.

Dark solitons, dispersive shock waves, and transverse instabilities

, 2011
The nature of transverse instabilities to dark solitons and dispersive shock waves for the (2+1)-dimensional defocusing nonlinear Schrodinger equation / Gross-Pitaevskii (NLS / GP) equation is considered. Special attention is given to the small (shallow)
