摘要

研究了旋转磁化等离子体与携带轨道角动量（OAM）的扭转阿尔弗文波之间的角动量耦合。研究不仅证明了旋转是携带轨道角动量的阿尔弗文波的菲涅尔-法拉第旋转（或轨道法拉第旋转效应）的来源，而且证明了携带轨道角动量的阿尔弗文波的角动量可以通过逆过程转移到旋转等离子体中。对于直接过程，横向结构角旋转频率是通过考虑 OAM 含量相反的模式的色散关系得出的。对于逆过程，等离子体上施加的转矩是作为波和等离子体参数的函数推导出来的。

Rotating Alfvén waves in rotating plasmas

Angular momentum coupling between a rotating magnetized plasma and torsional Alfvén waves carrying orbital angular momentum (OAM) is examined. It is demonstrated not only that rotation is the source of Fresnel–Faraday rotation – or orbital Faraday rotation effects – for OAM-carrying Alfvén waves, but also that angular momentum from an OAM-carrying Alfvén wave can be transferred to a rotating plasma through the inverse process. For the direct process, the transverse structure angular rotation frequency is derived by considering the dispersion relation for modes with opposite OAM content. For the inverse process, the torque exerted on the plasma is derived as a function of wave and plasma parameters.

期刊介绍： JPP aspires to be the intellectual home of those who think of plasma physics as a fundamental discipline. The journal focuses on publishing research on laboratory plasmas (including magnetically confined and inertial fusion plasmas), space physics and plasma astrophysics that takes advantage of the rapid ongoing progress in instrumentation and computing to advance fundamental understanding of multiscale plasma physics. The Journal welcomes submissions of analytical, numerical, observational and experimental work: both original research and tutorial- or review-style papers, as well as proposals for its Lecture Notes series.
