摘要

我们收集并描述了观测到的量子流体中湍流的几何和动力学性质,特别是超流氦和原子凝聚体,其中湍流的更多信息是可用的。考虑到谱特征、时间衰减以及与相关经典湍流的比较,我们确定了三种主要的量子湍流限制类型:Kolmogorov量子湍流、Vinen量子湍流和强量子湍流。这种分类将有助于分析和解释这些和其他量子流体的新结果。

Types of quantum turbulence
We collect and describe the observed geometrical and dynamical properties of turbulence in quantum fluids, particularly superfluid helium and atomic condensates for which more information about turbulence is available. Considering the spectral features, the temporal decay, and the comparison with relevant turbulent classical flows, we identify three main limiting types of quantum turbulence: Kolmogorov quantum turbulence, Vinen quantum turbulence, and strong quantum turbulence. This classification will be useful to analyze and interpret new results in these and other quantum fluids.
