The paper demonstrates the existence of modulational instability (MI) in nonlinear exciton-
polariton condensates (EPCs). A set of coupled two-dimensional (2D) driven-dissipative …

Abstract n this research paper under consideration is the nonlinear multi-core coupler
(coupling with all neighbors) with the parabolic law nonlinearity and optical metamaterials …

We have investigated wave solutions of the Predator–Prey (PP) model with fractional
derivative order by novel three modified mathematical methods with the help of the …

This work addresses the analytical investigation of the prey–predator behavior modeled by
nonlinear evolution equation systems with fractional derivative order. Through the New …

This paper shows out optical soliton solutions of the twin-core couplers with parabolic law
nonlinearity with optical metamaterials parameters. It is used the improved new sub-ODE …

The letter explores modulational instability (MI) in birefringent optical media with pure-
quartic dispersion, relaxed Kerr nonlinearity, and walk-off effects. The linear stage of MI is …

We investigate the modulation instability of two incoherently copropagating optical waves in
a nonlinear fiber taking into account the relaxing Kerr nonlinearity, walk-off effects, delay …

In this paper, we intend to carry out a detail investigation on influence of higher-order effects
on the modulation instability scenario in the three-core triangular (NIM-PIM-NIM) oppositely …

The synchronization of spatial modes in the formation of multimode solitons can be
considered as the transverse analog of mode locking. In this process, the inherent Kerr …

We present a two-dimensional coupled nonlinear Schrödinger-like system with spatial
diffractions, degree of birefringence, and four-wave mixing. This system describes two …
