Generation of Acoustic Rogue Waves in Dusty Plasmas through Three-Dimensional Particle Focusing by Distorted Waveforms
Rogue waves are rare uncertainly emerging localized events with large amplitudes, and their presence has been observed in many physical phenomena. Phenomena such as water waves, many nonlinear wave phenomena, optical waves and ion acoustic waves. The study of these waves has previously been carried out with a focus on 1D wave behavior through modulation instabilities. one of the fundamental issues and questions that needs attention is whether rogue waves also exist in nonlinear 3D acoustic-type plasma waves, the kinetic origin of their formation and their correlation with surrounding 3D waveforms. This talk will focus on direct experimental observation of dust acoustic rogue waves in dusty plasmas and constructing a picture of 3D particle focusing by the surrounding tilted and ruptured wave crests, associated with the higher probability of low-amplitude holes for rogue-wave generation.
