Scientists Observe and Control Kelvin Waves in Superfluid Helium for the First Time

In a groundbreaking study, researchers have controlled and observed Kelvin waves in superfluid helium-4 for the first time. Using an electric field to manipulate nanoparticles trapped in vortex lines, they generated and visualised the helical motion of these quantum waves. This discovery sheds light on energy dissipation in superfluid systems and opens new avenues for...
