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 ... The interplay between the superfluid phases and the presence of vortices, as well as the role of aerogels, has led to significant ...

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 ...

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 ...

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, ...

Lord Kelvin theorized in 1880 that stimulating a thin vortex line would produce a helical deformation, later known as a ...
