Abstract:
We investigate dust-acoustic rogue waves in a one-dimensional binary dusty plasma using analytical nonlinear Schrödinger equation theory and fully kinetic particle-in-cell simulations. Modulational instability initially drives nonlinear focusing and rogue-wave formation, consistent with fluid predictions. However, after the rogue-wave peak, the coherent structure collapses irreversibly due to kinetic effects instead of exhibiting periodic recurrence. The breakdown is caused by asymmetric kinetic heating between the two dust species. The lighter dust grains, owing to their lower inertia, absorb most of the wave energy through strong wave-particle interactions and develop non-Maxwellian energetic tails, while the heavy dust experiences only weak heating. In addition, the rogue-wave excitation time is highly sensitive to small changes in the imposed perturbation amplitude. These results demonstrate the kinetic and irreversible nature of rogue waves in realistic binary dusty plasmas.
