Velocity Statistics Distinguish Quantum Turbulence from Classical Turbulence
Velocity Statistics Distinguish Quantum Turbulence from Classical Turbulence
By analyzing trajectories of solid hydrogen tracers, we find that the distributions of velocity in decaying quantum turbulence in superfluid $^{4}\mathrm{He}$ are strongly non-Gaussian with $1/{v}^{3}$ power-law tails. These features differ from the near-Gaussian statistics of homogenous and isotropic turbulence of classical fluids. We examine the dynamics of many events …
