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 ...
Kelvin waves have been a mystery for decades but a new method involving superfluid helium-4 can help us control them.
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 ...
Scientists have controlled Kelvin waves in superfluid helium-4, using electric fields and nanoparticles to visualize them, ...
So they created tiny silicon particles in superfluid helium-4 by hitting a silicon wafer with a laser. This action disturbed the fluid, trapping some particles in vortex cores, and making the vortices ...
Scientists demonstrate controlled oscillations of quantum vortex core lines in superfluid helium, visualizing helical waves on quantum vortices.
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 ...
