<p>This work studies the dynamical behaviors of the generalized nonlinear evolution equation (GNLEE) introduced by Chen (2003), which is significant in explaining superconductivity in steady ion-cyclotron waves in nonhomogeneous plasma and drift cyclotron waves. This study investigates the model's dynamic properties using both analytical and numerical methods, with a focus on bifurcation analysis. First, wave transformation is used to convert the model into its standard form. This approach helps predict the creation or disappearance of equilibrium arguments, limit cycles, and soliton structures. The system's dynamic behavior is then analyzed using phase and Hamiltonian portraits for different parameter values. Furthermore, we identify dark-type bell-wave, bright periodic, kink, bright-type, anti-kink, and solitary-wave solutions by manipulating parameters, using their Hamiltonians, and integrating heteroclinic and homoclinic orbits. The visual representation of these characteristics is achieved by carefully selecting the appropriate parameters. Finally, the MI also studies the proposed model to explain how small changes in field amplitude give rise to solitary structures, domain walls, and vortices. MI study of the Landau–Ginsburg–Higgs model shows how nonlinear interactions influence wave evolution and establish stability constraints in optical, quantum, and cosmic environments. From the above analysis, the applied method is more effective at capturing complex phenomena.</p>
