二维流体等离子体中哈密顿磁力线重联的非线性演化导致了具有有限尺寸岛和精细尺度空间结构的宏观平衡。后者产生的拉格朗日不变场的相位混合。该平衡类似于静电朗缪尔波的Bernstein-Greene-Kruskal平衡解。
The nonlinear evolution of a Hamiltonian magnetic field line reconnection in a two-dimensional fluid plasma leads to a macroscopic equilibrium with a finite-size island and fine-scale spatial structures. The latter arise from the phase mixing of the Lagrangian invariant fields. This equilibrium is the analog of the Bernstein-Greene-Kruskal equilibrium solution for electrostatic Langmuir waves.
