Parallel measurements of the viscosity of helium II and helium gas in the corresponding ... energy state will perform-like a 'superfluid' liquid of viscosity (JL ^ 0-some sort of turbulent motion ...

The findings, published in arXiv, stem from high-precision experiments with superfluid helium, a quantum liquid known for its ability to flow without viscosity. Unlike the familiar heat diffusion ...

Abstract: High frequency Rayleigh and Sezawa modes propagating in the ZnO/GaAs system capable of operating immersed in liquid helium have been engineered. In the case of the Rayleigh mode, the strong ...

N. Kürti, B. V. Rollin and F. Simon 1 found that below the λ-point liquid helium slips over the surface of the tube lowered into it. They observed this phenomenon by increasing the flow of heat ...

Abstract: Breakdown statistics in liquid helium have been evaluated in order to correlate with size effect degradation, i.e. the area and the volume effect, respectively. Reprocessing large number of ...

The viscosity of iron alloy liquids is the key for the core dynamo and core-mantle differentiation of terrestrial bodies. Here we measured the viscosity of Fe-Ni-C liquids up to 7 GPa using the ...

A superfluid is a special liquid that moves without viscosity. In helium-4, this behavior appears at temperatures below about −456 °F (-271°C). When the fluid is both superfluid and normal, friction ...

A liquid bowel movement (diarrhea) is usually related to a short-term health challenge like food poisoning or a virus. It may also be related to a chronic condition. Diarrhea can happen to ...

Scientists are pushing the bounds further each and every day. Now, an Italian team created supersolid light, which could have ...

The Luttinger Model is the only model of many-fermion physics with legitimate claims to be both exactly and completely solvable. In several respects it plays the same role in many-body theory as does ...
