摘要

本文研究了非均匀复杂等离子体中的瑞利-泰勒(RT)不稳定性。已经观察到，当尘埃颗粒的质量密度在某些区域表现出不均匀性时，可能会发生RT不稳定性。随摄动波长的减小和重力加速度的增大，RT不稳定性的增长率增大。此外，还发现尘埃流体的带电特性在抑制复杂等离子体中RT不稳定性方面起着重要作用。我们的研究结果在复杂等离子体中有潜在的应用前景。

Rayleigh–Taylor Instability and Its Growth Rate in Complex Plasmas

Rayleigh–Taylor (RT) instability is studied in this article in an inhomogeneous complex plasma. It has been observed that RT instability may occur when the mass density of the dust particles exhibits inhomogeneity in certain regions. The growth rate of the RT instability increases as the perturbed wavelength decreases and also as the gravitational acceleration increases. Moreover, it is also found that the charged characteristics of dust fluids play an important role in suppressing the RT instability in complex plasmas. Our results have potential applications in complex plasmas.
