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

Moreover, direct visualization techniques have been employed to observe the structure and dynamics of quantum vortices in rotating superfluid helium. These studies have confirmed theoretical ...

Superfluid helium-3 (³He) is a fascinating state of ... The interplay between the superfluid phases and the presence of vortices, as well as the role of aerogels, has led to significant ...

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

and even form stable vortices. Superfluid helium, with its zero viscosity, not only defies gravity by climbing the inside walls of the container but also completes a gravity-defying cycle by dripping ...

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 ...

Kelvin waves have been a mystery for decades but a new method involving superfluid helium-4 can help us control them.

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