In a new study published in Nature Physics, researchers have developed the first controlled method for exciting and observing ...

Superfluid helium-3 (³He) is a fascinating state of ... particularly in the context of vortex dynamics and the effects of aerogels—lightweight, porous materials that can influence the ...

This article was originally published with the title “ Quantized Vortex Rings in Superfluid Helium ” in Scientific American Magazine Vol. 211 No. 6 (December 1964), p. 116 doi:10.1038 ...

For instance, experiments have shown that a toroidal bundle of vortex rings in superfluid helium can create a large-scale wake in the surrounding normal fluid, which reduces friction and enhances ...

Scientists demonstrate controlled oscillations of quantum vortex core lines in superfluid helium, visualizing helical waves on quantum vortices.

This phenomenon occurs in certain quantum fluids, such as liquid helium-4 below a critical temperature of 2.17 K (-270.98 °C). In the superfluid state, the fluid can flow through narrow channels ...

Turbulence can also occur in sound waves that propagate chaotically in certain media, such as superfluid helium. In the 1970s, Soviet scientists proposed that turbulence occurs when sound waves ...

A team of Japanese researchers has discovered a method to control Kelvin wave excitation in superfluid helium-4. This breakthrough can refine our understanding of how energy moves in quantum fluids, ...

Scientists have controlled Kelvin waves in superfluid helium-4, using electric fields and nanoparticles to visualize them, ...
