The most common example of a superfluid is helium-4 ... dissipate as heat like in traditional fluids. The solution is Kelvin waves. For the formation of Kelvin waves, the researchers start ...

later known as a Kelvin wave. While these waves have been observed in classical fluids like water and air, their existence in quantum fluids has remained largely theoretical due to the extreme ...

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