Quantum turbulence—the stochastic motion of quantum fluids such as 4He and 3He-B,
which display pure superfluidity at zero temperature and two-fluid behavior at finite but low …

Turbulence under strong influence of rotation is described as an ensemble of interacting
inertial waves across a wide range of length scales. In macroscopic quantum condensates …

Generic scaling laws, such as Kolmogorov's 5/3 law, are milestone achievements of
turbulence research in classical fluids. For quantum fluids such as atomic Bose–Einstein …

Flow visualization using particle image velocimetry (PIV) and particularly particle tracking
velocimetry (PTV) has been applied to thermal counterflow in He II for nearly two decades …

Acoustic black holes (ABHs) have garnered increasing attention in the field of vibration and
noise reduction due to their excellent wave aggregation effect. A large number of studies …

In classical viscous fluids, turbulent eddies are known to be responsible for the rapid
spreading of embedded particles. However, in inviscid quantum fluids where the turbulence …

In a 2D turbulent fluid containing pointlike vortices, Lars Onsager predicted that adding
energy to the fluid can lead to the formation of persistent clusters of like-signed vortices, ie …

There are two commonly discussed forms of quantum turbulence in superfluid He 4 above 1
K: in one there is a random tangle of quantized vortex lines, existing in the presence of a …

Intermittency is a hallmark of turbulence, which exists not only in turbulent flows of classical
viscous fluids but also in flows of quantum fluids such as superfluid He 4. Despite the …

Despite being a quantum two-fluid system, superfluid helium-4 (He II) is observed to behave
similarly to classical fluids when a flow is generated by mechanical forcing. This similarity …
