In a new study published in Nature Physics, researchers have developed the first controlled method for exciting and observing Kelvin waves in superfluid helium-4. First described by Lord Kelvin in ...

Superfluid helium-3 (³He) is a fascinating state of matter that exhibits unique properties at extremely low temperatures. It exists in different phases, each characterized by distinct behaviors ...

Quantum turbulence is a fascinating phenomenon that occurs in superfluid helium, a state of matter that exhibits unique properties at extremely low temperatures. Unlike classical turbulence ...

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 ...

Superfluidity is a state of matter characterized by the complete absence of viscosity, allowing the fluid to flow without friction. This phenomenon occurs in certain quantum fluids, such as liquid ...

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, ...
