Not exact matches
If at the boundary the superfluids continued to rotate faster on the inside, then the two semicircles would start to twist, elongating the line that separates them, and thus requiring more energy to stay separated.
The researchers have rotated a container filled with superfluid helium - 3 isotopes near absolute zero temperature.
But only the normal fraction will rotate with the cylinder, because of friction between it and the cylinder walls; the superfluid portion cuts right through the normal fluid and remains still.
The superfluid fraction will not rotate.
Rotating the disk forward and back makes the superfluid helium flow around in the cavity, and the amount that is superfluid can be observed as a change in the period of oscillation of the disk.
