Unveiling of Highly Dispersive Dual-Solitons and Modulation Instability Analysis for Dual-Mode Extension of a Non-Linear Schrödinger Equation

Contemporary Mathematics
The two-mode equations are nonlinear models that describe the behavior of two-way waves moving simultaneously while being affected by confined phase velocity. This article expands a non-linear Schrödinger equation (NLSE) by constructing it as a dual-mode

The Fermi-Pasta-Ulam recurrence and related phenomena for 1D shallow-water waves in a finite basin

, 2011
In this work, different regimes of the Fermi-Pasta-Ulam (FPU) recurrence are simulated numerically for fully nonlinear "one-dimensional" potential water waves in a finite-depth flume between two vertical walls.

Dynamics of Solitons and Quasisolitons of Cubic Third-Order Nonlinear Schr\"odinger Equation

, 2001
The dynamics of soliton and quasisoliton solutions of cubic third order nonlinear Schr\"{o}dinger equation is studied. The regular solitons exist due to a balance between the nonlinear terms and (linear) third order dispersion; they are not important at ...

Efficiency of dispersive wave generation in dual concentric core microstructured fiber

, 2015
We describe the generation of powerful dispersive waves that are observed when pumping a dual concentric core microstructured fiber by means of a sub-nanosecond laser emitting at the wavelength of~1064 nm.

PROCESSES OF FORMATION OF SOLITON COMPLEXES AND BREATHERS IN HIGHLY DISPERSIVE MEDIA

Scientific Herald of Uzhhorod University.Series Physics, 2007
Peculiarities of dynamics of topological solitons (kinks) and mechanisms of foma- tion of their bound complexes are investigated analytically and numerically in the framework of the sine-Gordon and double sine-Gordon equations with the fourth- order spatial-temporal derivative.

Nonlinear Polariton Fluids in a Flatband Reveal Discrete Gap Solitons

, 2019
Phase frustration in periodic lattices is responsible for the formation of dispersionless flat bands. The absence of any kinetic energy scale makes flat band physics critically sensitive to perturbations and interactions.

Measurement of scaling laws for shock waves in thermal nonlocal media

, 2012
We are able to detect the details of spatial optical collisionless wave-breaking through the high aperture imaging of a beam suffering shock in a fluorescent nonlinear nonlocal thermal medium.

Communication-ready high-power soliton microcombs in highly-dispersive Fabry-Perot-microresonators

Microcombs generated in optical microresonators are widely regarded as promising light sources for next-generation communication systems, but the optical power available per comb line has so far fallen short of practical requirements. Here we introduce an integrated Fabry-Pérot microresonator platform that overcomes fundamental dispersion-engineering ...
