- 論文の詳細を見る
The nonlinear evolution of an ion-acoustic wave packet is studied. Experimentally we find that (i) nonlinear phasemodulation develops in the wave packet; (ii) the phasemodulation, together with the dispersion effect, causes expansion, and breaking of the wave packet; (iii) the ions trapped in the troughs of the wave potential introduce self-phase-modulation, and (iv) the ion-acoustic wave is stable with respect to the modulational instability. Computer simulations have reproduced the experimental findings. The physical picture and the model equation describing the wave evolution are discussed.
