在圆柱形磁化等离子体中观察到了漂移波涨落的聚束流光及其与其他涨落耦合产生流光的介体。用两相分析方法详细研究了它们的径向结构。它们的准二维结构与基于长谷川-米玛模型的非线性薛定谔方程所预测的一对快模和慢模是等价的。
A streamer, which is a bunching of drift-wave fluctuations, and its mediator, which generates the streamer by coupling with other fluctuations, have been observed in a cylindrical magnetized plasma. Their radial structures were investigated in detail by using the biphase analysis. Their quasi-two-dimensional structures were revealed to be equivalent with a pair of fast and slow modes predicted by a nonlinear Schrödinger equation based on the Hasegawa-Mima model.
