Modulational-Stability Topology and Symmetric Instability Spectra in Non-Maxwellian Heavy Ion-Acoustic Plasmas: Akhmediev Breathers and Higher-Order Rogue Waves
This paper presents a comprehensive analytical and numerical investigation of the cubic nonlinear Schrödinger equation derived from the heavy ion-acoustic wave (HIAW) model, which governs the evolution of weakly nonlinear wave packets and their chaotic envelope dynamics. The modulational instability (MI), symmetric ins...
