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, ...
Draining the water from a bathtub causes a spinning tornado to appear. The downward flow of water into the drain causes the water to rotate, and as the rotation speeds up, a vortex forms that obeys ...
In a new study published in Nature Physics, researchers have developed the first controlled method for exciting and observing ...
