From: Acceleration of ion phase-space holes due to interactions with ion solitons in a wave-guided plasma
Formation and propagation of an ion phase-space hole (negative pulse moving to the left) and an ion KdV soliton (positive pulse moving to the left). (a) Potential fields at time steps of \(3.4288 \omega _{pi}^{-1}\) (starting from top, time \(=3.4288 \omega _{pi}^{-1}\)) and (b) corresponding phase-space density portraits. (c) Spatio-temporal portrait of wave potentials exhibiting wave propagation. Ion soliton (pink-blue wave) and ion hole (thin, green wave propagating to left) can be seen. Stability of ion hole potential amplitude is shown from the color gradient, whereas the ion soliton exhibits a decay in its amplitude.
