Composites consisting of metal nanoparticles (NPs) embedded in dielectric media may
present large nonlinear optical response due to electronic transitions in the NPs. When the …

In this paper, the modulational instability of the one-dimensional optical soliton has been
studied in the presence of Gaussian and sine oscillatory nonlocal response functions. By …

The modulational instability (MI) of continuous waves is exclusively addressed theoretically
and numerically in a two-component Bose-Einstein condensate in the presence of a mixture …

The paper studies the modulational instability (MI), both theoretically and numerically, of the
helicoidal spin-orbit coupled Bose-Bose mixture. An expression of the MI growth rate is …

Considering the theory of electromagnetic waves from the Maxwell's equations, we
introduce a (3+ 1)-dimensionsal cubic-quintic complex Ginzburg-Landau equation …

We establish the condition of modulational instability (MI) in one-dimensional effective one-
component self-bound quantum droplets and Bose–Bose (BB) mixture, coupled through …

In this paper, by means of the expanded Taylor series and Lindstedt-Poincaré perturbation
methods, the coupled nonlinear Schrödinger equations (CNLSE) modeling the propagation …

The influence of a saturable nonlinearity on the modulation instability (MI) in an oppositely
directed coupler in the presence of high-order effects is investigated. The instability gain is …

We investigate modulational instability (MI) in a planar dual-core waveguide (DWG), with a
Kerr and non-Kerr polarizations based on coupled nonlinear Schrödinger equations in the …

In this paper, we study Modulation Instability (MI) and its correlated gain spectrum with Parity-
Time (𝒫 𝒯)-symmetry. The cubic-quintic nonlinearities in the Bragg grating structure produce …
