Helium Vortices Reveal Quantum Behaviour at Varied Temperatures

Researchers at the University of Helsinki found that in superfluid helium, which flows smoothly without any friction, special spinning whirls can split in three different ways, depending on how cold it is. By using a special kind of theory called the gauge/gravity duality theory, they saw that these whirls split in two ways when it's super cold but might split in a new way when it's a bit less cold. This shows us how the cold affects the way these special whirls behave in the super smooth helium. This has applications in developing quantum computing which in turn can drive helium demand.
