Ion phase-space holes are solitary kinetic structures found in the ion phase-space of collision-less plasmas, and are nonlinear solutions to the Vlasov-Poisson equations, identified as Bernstein-Greene-Kruskal (BGK) modes. In this study, interactions between an ion phase-space hole and a travelling ion KdV soliton is presented. This interaction, which is simulated in a fully ionised highly magnetised plasma within a cylindrical wave-guide, exhibits acceleration and deacceleration of the ion hole, depending on its mode of collision with the travelling ion soliton. We present these interactions and discuss the mechanism of this interaction between the two solitary waves.
离子相空间空洞是在无碰撞等离子体的离子相空间中发现的孤立动力学结构，是弗拉索夫 - 泊松方程的非线性解，被识别为伯恩斯坦 - 格林 - 克鲁斯卡尔（BGK）模式。在本研究中，展示了离子相空间空洞与行进的离子KdV孤子之间的相互作用。这种相互作用是在圆柱形波导内的完全电离的高磁化等离子体中模拟的，根据离子空洞与行进的离子孤子的碰撞模式，表现出离子空洞的加速和减速。我们展示了这些相互作用，并讨论了这两种孤立波之间相互作用的机制。
