It is shown how to compute the instability rates for the double-periodic solutions to the cubic NLS (nonlinear Schrödinger) equation by using the Lax linear equations. The wave function …
The classical theory of modulation instability (MI) attributed to Bespalov–Talanov in optics and Benjamin–Feir for water waves is just a linear approximation of nonlinear effects and …

In this study, the analytical solution of the Hirota equation by using the rational sine–Gordon expansion method (RSGEM) has been investigated. For this purpose, the mentioned model …
We show that the nonlinear stage of the universal phenomenon of modulational instability, and in particular its recurrent behavior, is deeply affected by arbitrarily weak losses. Indeed …

In this study, a bilinear neural network method is used to solve the exact solutions of the (2+ 1)-dimensional Kadomtsev–Petviashvili equation, which is a new geophysical fluid …
We report the observation of the thermalization of the Fermi-Pasta-Ulam-Tsingou recurrence process in optical fibers. We show the transition from a reversible regime to an irreversible …

Abstract The Fermi–Pasta–Ulam–Tsingou recurrence phenomenon for the Ablowitz–Ladik equation is studied analytically and computationally. Wave profiles periodic in the discrete …
Rogue waves are anomalously high waves that may suddenly form on the sea surface. At the dawn of the 21st century, they attracted the interest of researchers, from oceanographers …
