论文摘要
提出了一个受银河磁盘结构的启发的新模型，用于在具有均匀有限背景磁场的等离子体中的三维Bernstein-Greene-kruskal（BGK）模式。这些模式是稳态弗拉索夫方程的确切非线性溶液，其电势和磁电势扰动局部在满足泊松方程的所有三个空间尺寸中，并且是自sonsemensiss的。在与磁盘物种相关的小型电场和磁场扰动的极限上进行了分析显示溶液的存在，并使用迭代方法进行数值，该方法收敛到中度强场扰动。
A new model, inspired by the structure of galactic disks, for three-dimensional Bernstein-Greene-Kruskal (BGK) modes in a plasma with a uniform finite background magnetic field is presented. These modes are exact nonlinear solutions of the steady-state Vlasov equation, with an electric potential and a magnetic potential perturbation localized in all three spatial dimensions that satisfies the Poisson equation, and the Ampere Law, self-consistently. The existence of solutions is shown analytically in the limit of small electric and magnetic field perturbations associated with the disk species, and numerically using an iterative method that converges up to moderately strong field perturbations.
