Superfluid helium: the quantum curiosity behind huge experiments like the LHC
Physics World Weekly Podcast
Exploring the Quantum World of Superfluid Helium
Delve into the unique quantum properties of superfluid helium, known as helium 2, which flows without viscosity and exhibits zero entropy, with applications in cooling superconducting magnets and RF cavities. The two fluid model of helium 2 simplifies understanding its properties, where a normal fluid component coexists with a superfluid component, each with distinct characteristics. Discover the efficient heat transfer properties of superfluid helium, its ability to flow uphill, and the fascinating phenomenon of a superfluid fountain.
