Energy Spectra of Developed Turbulence in Helium Superfluids
We suggest a minimal model for the 3D turbulent energy spectra in superfluids, based on their two-fluid description.

Velocity measurements of a superfluid helium flow through a channel generated by fountain effect
In superfluid helium a flow can be established by a temperature gradient, an effect which is sometimes used to drive fluid through chennels in turbulence studies. The problem of measuring the velocity of such flows naturally arises....

A simple phenomenological model for the effective kinematic viscosity of helium superfluids
A simple model is presented to estimate effective kinematic viscosity based on comparison of dissipation terms in equations of motion for classical viscous flow and vortex flow of superfluid in a stationary normal fluid....

On visualisation of counterflow quantum turbulence in superfluid helium
Standard visualisation techniques can usefully be applied for investigations of various flows of cryogenic helium, including superflows, with appropriately chosen tracking particles such as hollow glass spheres, polymer microspheres or solid...

Capillary-wave crystallography: Crystallization of two dimensional sheets of He+ ions
We report an experimental study of the crystallization of sheets of positive ions trapped below the surface of superfluid helium. The technique relies on the generation and interference of capillary waves on the helium surf...
