摘要

基于动力学理论，在非广延性分布的背景下研究了未磁化系统中的非稳态卡普曼-瓦希米思动力和自生磁场。得到了思动力、磁化和辐射功率作为非广延性参数 q、波频和波数的函数。结果表明，高速电子的存在会导致思向力、磁化和辐射功率的时空变化部分增加。此外，结果表明卡普曼-瓦希米思动力驱动的自生磁场主要表现为小尺度和低频磁场。

Karpman–Washimi ponderomotive force and self-generated magnetic field in nonextensive plasmas

The non-stationary Karpman–Washimi ponderomotive force and self-generated magnetic field in an unmagnetized system are investigated in the context of nonextensive distribution based on the kinetic theory. The ponderomotive force, magnetization, and radiation power are obtained as functions of the nonextensive parameter q, wave frequency, and wave number. It is shown that the presence of high-velocity electrons leads to an increase in temporal and spatial variation parts of ponderomotive force, magnetization, and radiation power. Furthermore, the results indicate that the self-generated magnetic field driven by the Karpman–Washimi ponderomotive force primarily manifests as small-scale and low-frequency magnetic field.

期刊介绍： AIP Advances is an open access journal publishing in all areas of physical sciences—applied, theoretical, and experimental. All published articles are freely available to read, download, and share. The journal prides itself on the belief that all good science is important and relevant. Our inclusive scope and publication standards make it an essential outlet for scientists in the physical sciences. AIP Advances is a community-based journal, with a fast production cycle. The quick publication process and open-access model allows us to quickly distribute new scientific concepts. Our Editors, assisted by peer review, determine whether a manuscript is technically correct and original. After publication, the readership evaluates whether a manuscript is timely, relevant, or significant.
