涨落耗散定理(FDT)是一个重要的和优雅的工具,以确定在热等温等离子体中的电磁涨落的强度,在宇宙和实验室等离子体中经常遇到的情况。由于人们对强阻尼振荡,特别是ωR = 0的非周期振荡的涨落很感兴趣,本文确定了磁化等离子体中任意复频率ω=ωR+iΓ的一般振荡的FDT。与弱阻尼相反,非周期涨落谱依赖于麦克斯韦算符元素的厄米(而不是反厄米)部分。在非磁化等离子体中FDT的显式表达式导出的纵向和横向的热色散函数。
The fluctuation-dissipation theorem (FDT) is an important and elegant tool to determine the intensity of electromagnetic fluctuations in thermal equal-temperature plasmas, a situation often encountered in cosmic and laboratory plasmas. As there is high interest in the fluctuations from stronger damped oscillations, especially aperiodic ones with ωR = 0, the FDT for general oscillations in magnetized plasmas for arbitrary complex frequencies ω=ωR+iΓ is determined. Contrary to weakly damped, the aperiodic fluctuation spectra depend on the Hermitian (instead of the anti-Hermitian) part of the elements of the Maxwell operator. Explicit expressions for the FDT in unmagnetized plasmas are derived in terms of the longitudinal and transverse thermal dispersion functions.
