Looking Inside the Superfluid Helium-3 Universe

Looking Inside the Superfluid Helium-3 UniverseA camera that can capture the internal structure of superfluid helium-3 will improve our understanding of the turbulent motion of quantum fluids.By Vladimir Eltsov W hen liquid helium-3 is cooled to millikelvin temperatures, it transitions into a state of matter called a superfluid.From the outside, superfluid helium-3 looks like a simple, transparent medium.Nevertheless, its internal structure is extremely rich and is often described as "the Universe in a droplet" [1].In helium-3, some atoms collectively play the role of the quantum vacuum-the
