The Sensational Experience of Touching a Quantum Superfluid

Physicists have conducted an experiment using a finger-sized probe to study the properties of a quantum superfluid, specifically helium-3. They discovered that the superfluid forms a two-dimensional layer on its surface that transports heat away from the probe, while the bulk of the superfluid remains passive and feels empty. This finding redefines our understanding of superfluid helium-3 and has implications for the study of collective matter states and quantum energy states. The research has the potential to transform our understanding of this macroscopic quantum system.
