AI中文摘要:
通过在方位角和z方向不变的设定下工作,我们将双物种弗拉索夫-麦克斯韦(VM)方程的电中性、磁驱动平衡态的存在性,简化为径向变量的二阶常微分方程组。与以往研究不同,我们考虑对应等离子体物理中z箍缩、θ箍缩和螺旋箍缩平衡态的特定物理场景,并给出这些场景下的半显式解。
英文摘要:
By working in a setting of azimuthal and $z$-directional invariance, we reduce the existence of electrically neutral, magnetically driven, equilibria of the two-species Vlasov-Maxwell (VM) equation to a second-order ODEs in the radial variable. In contrast to previous works, we consider specific situations that correspond physically to $z$-pinch, $θ$-pinch, and screw-pinch equilibria in plasma physics. Semi-explicit solutions in these situations are provided.
