Special Issue Information

Dear Colleagues,

Optical solitons are commonly known in all-optical ultrafast switching systems and the protracted communication after being conceived and validated practically. As a result, it has piqued the interest of a majority of nonlinear optics researchers. In diverse sectors, such as applied sciences, mathematical photonics, nonlinear wave propagation, and plasma physics, partial differential equations (PDEs) can be employed to quantify a plethora of dynamical systems. The quest for their numerical and analytical solutions provides the most insightful discussion about these equations and the nonlinear physical phenomena they are linked to.

In interacting systems, symmetry is frequently utilized to establish conservation principles and to create forbidden/allowed transitions. Symmetries are commonly employed in the field of nonlinear optics to identify whether a specific nonlinear process is permitted or prohibited based on the point group of the medium.

Our primary driving force behind this Special Issue is to look for various wave shapes for the PDEs' achieved solutions. To accomplish our objective, we use different analytical or numerical techniques to identify several analytical (or numerical) solutions, such as solitary, kink-soliton, anti-kink soliton, shock, dark-soliton, bright-soliton, and elliptic wave solutions. Topics of interest include (but are not limited to): nonlinear optics, wave transmission and propagation in homogeneous and inhomogeneous materials, and optical properties of materials.

Abstract
We study the (3+1)-dimensional stochastic Jimbo–Miwa (SJM) equation induced by multiplicative white noise in the Itô sense. We employ the Riccati equation mapping and He’s semi-inverse techniques to provide trigonometric, hyperbolic, and rational function solutions of SJME. Due to the applications of the [...] Read more.
We study the (3+1)-dimensional stochastic Jimbo–Miwa (SJM) equation induced by multiplicative white noise in the Itô sense. We employ the Riccati equation mapping and He’s semi-inverse techniques to provide trigonometric, hyperbolic, and rational function solutions of SJME. Due to the applications of the Jimbo–Miwa equation in ocean studies and other disciplines, the acquired solutions may explain numerous fascinating physical phenomena. Using a variety of 2D and 3D diagrams, we illustrate how white noise influences the analytical solutions of SJM equation. We deduce that the noise destroys the symmetry of the solutions of SJM equation and stabilizes them at zero. Full article

The present work is attentive to studying the qualitative analysis for a nonlinear strain wave equation describing the finite deformation elastic rod taking into account transverse inertia, and shearing strain. The strain wave equation is rewritten as a dynamic system by applying a particular transformation. The bifurcation of the solutions is examined, and the phase portrait is depicted. Based on the bifurcation constraints, the integration of the first integral of the dynamic system along specified intervals leads to real wave solutions. We prove the strain wave equation has periodic, solitary wave solutions and does not possess kink (or anti-kink) solutions. In addition, the set of discovered solutions contains Jacobi-elliptic, trigonometric, and hyperbolic functions. This model contains many kinds of solutions, which are always symmetric or anti-symmetric in space. We study how the change in the physical parameters impacts the solutions that are found. Numerically, the behavior of the strain wave for the elastic rod is examined when particular periodic forces act on it, and moreover, we clarify the existence of quasi-periodic motion. To clarify these solutions, we present a 3D representation of them and the corresponding phase orbit. Full article

Stochastic partial differential equations have wide applications in various fields of science and engineering. This paper addresses the optical stochastic solitons and other exact stochastic solutions through birefringent fibers for the Biswas–Arshed equation with multiplicative white noise using the modified extended mapping method. This model contains many kinds of soliton solutions, which are always symmetric or anti-symmetric in space. Stochastic bright soliton solutions, stochastic dark soliton solutions, stochastic combo bright–dark soliton solutions, stochastic combo singular-bright soliton solutions, stochastic singular soliton solutions, stochastic periodic solutions, stochastic rational solutions, stochastic Weierstrass elliptic doubly periodic solutions, and stochastic Jacobi elliptic function solutions are extracted. The constraints on the parameters are considered to guarantee the existence of these stochastic solutions. Furthermore, some of the selected solutions are described graphically to demonstrate the physical nature of the obtained solutions. Full article
