Modulated blood waves in the coupled complex Ginzburg-Landau equations of Jeffrey fluids in arteries

C. D. Bansi Kamdem et al.

Summary: Modulational instability of continuous-wave solutions in Jeffrey fluids is investigated for its application in blood flow in arteries. The study utilizes multiple-scale expansion to examine backward propagating dissipative blood waves, which are described by a set of nonlinearly coupled complex Ginzburg-Landau equations. Different characteristics of the modulational instability, including the gain spectrum, are studied under low and high viscous effects. It is observed that increasing the viscosity coefficient leads to an enlargement of the instability bandwidth.

Modulational instability in two-dimensional dissipative open Bose-Einstein condensates with mixed helicoidal and Rashba-Dresselhaus spin-orbit couplings

Conrad Bertrand Tabi et al.

Summary: The letter proposes a modified set of coupled 2D CGL equations that include Rashba and Dresselhaus as well as helicoidal SOCs and study matter-wave formation in 2D BECs using MI. The linear stability analysis provides an expression for the MI gain, and the parametric study explores the effects of the included SO coupling. Numerical simulations confirm analytical predictions and demonstrate the emergence of dissipative nonlinear patterns in a wide range of structures due to effective energy exchange between the two BEC components.

Modulational instability in vector exciton-polariton condensates with photonic spin-orbit coupling

Edmond B. Madimabe et al.

Summary: This paper demonstrates the existence of modulational instability in nonlinear exciton-polariton condensates. The growth rate expression is derived through linear stability analysis of continuous waves, and a parametric study of modulational instability is conducted. The results show that the photonic spin-orbit coupling and the pumping power have an impact on the growth rate spectrum.

Interplay between spin-orbit couplings and residual interatomic interactions in the modulational instability of two-component Bose-Einstein condensates

Conrad Bertrand Tabi et al.

Summary: This study investigates the nonlinear dynamics induced by the modulation instability of a binary mixture in an atomic Bose-Einstein condensate, considering the effects of higher-order residual nonlinearities and helicoidal spin-orbit coupling. The analysis is based on modified coupled Gross-Pitaevskii equations, and the stability of plane-wave solutions is studied to obtain the modulation instability gain. Parametric analysis reveals regions of instability and the effects of higher-order interactions and spin-orbit coupling under different combinations of interaction strengths. Numerical calculations support the analytical predictions, showing that the residual nonlinearity can preserve and reinforce the stability of miscible pairs of condensates with spin-orbit coupling.

(2+1)-dimensional unstable matter waves in self-interacting pseudospin-1/2 BECs under combined Rashba and Dresselhaus spin-orbit couplings

Conrad Bertrand Tabi et al.

Summary: The modulational instability of continuous waves in a two-component Bose-Einstein condensate with a mixture of Rashba and Dresselhaus spin-orbit couplings and the Lee-Huang-Yang term is investigated theoretically and numerically. It is found that instability can be induced in the presence of the RD spin-orbit coupling under suitable balance between nonlinear and dispersive effects. The emergence of multi-peaked solitons and exotic vortex structures in direct numerical simulations confirms the analytical predictions and suggests that modulational instability is a suitable mechanism for generating matter waves.

Modulation instability of two-dimensional Bose-Einstein condensates with helicoidal and a mixture of Rashba-Dresselhaus spin-orbit couplings

Conrad Bertrand Tabi et al.

Summary: In this study, the modulational instability process is investigated in a two-component Bose-Einstein condensate with Rashba-Dresselhaus spin-orbit and helicoidal couplings. The dynamics of the condensate in a square lattice is addressed using a generalized set of two-dimensional Gross-Pitaevskii equations. The growth rate of modulational instability is derived and parametric analyses show the dependence on interatomic interaction strengths and the coupling parameters. Numerical simulations confirm the analytical predictions and reveal the behavior of solitons under varying coupling parameters.

Generation of dissipative solitons in a doped optical fiber modeled by the higher-order dispersive cubic-quintic-septic complex Ginzburg-Landau equation

Dieudonne Zanga et al.

Summary: This article explores the generation of dissipative optical solitons in doped fibers with correction effects under the activation of modulational instability (MI). The model used includes higher-order dispersion and nonlinear gradient terms, and the Lange-Newell's criterion, boundary domains, and integrated gain of MI are obtained via linear stability analysis. The physical effect on the critical frequency detuning is studied, particularly in the normal regime, by varying the values of odd dispersion coefficients. Numerical simulations are conducted and compared to analytical predictions, and the soliton map induced by MI and its subsequent physical effects are discussed using bifurcation diagrams. The article argues that understanding the center of mass and energy of the generated structures can better characterize the long-time evolution of MI and its nonlinear manifestations.

Summary: This paper focuses on the interaction between an electromagnetic field and matter in a laser cavity without assuming a fixed direction of the transverse electric field. It reports the derivation of a vectorial cubic-quintic complex Ginzburg-Landau equation and analyzes the stability of moving dissipative solitons in the laser cavity. The obtained results have potential applications in all-optical data processing systems and class B lasers.

Modulation instability in the presence of slowly varying saturable nonlinearity, dispersion and a PT-symmetric external potential over the length of waveguide

Vivek Kumar Sharma

Summary: This study investigates the modulation instability of optical wave propagation in tapered graded-index waveguide with slowly varying saturable nonlinearity, dispersion, and PT-symmetric external potential. The research analyzes the growth rate of MI for both focussing and defocussing nonlinearities with different choices of dispersion and saturated nonlinearity, observing that MI gain decreases with cw amplitude but increases with saturated nonlinearity. The presence of PT symmetric potential has no significant impact on MI, indicating that MI is primarily influenced by dispersion, nonlinearities, and wave amplitude.

Generation of matter waves in Bose-Bose mixtures with helicoidal spin-orbit coupling

Conrad Bertrand Tabi et al.

Summary: The paper investigates the modulational instability (MI) of helicoidal spin-orbit coupled Bose-Bose mixtures both theoretically and numerically. It identifies the growth rate of MI through linear stability analysis and explores the effects of spin-orbit coupling, helicoidal gauge potential, and interatomic interactions on MI regions. The study finds that under proper balance between nonlinear and dispersive effects, solitonlike objects can be obtained with sensitivities to parameter variations.
