Superfluids

Surprising entropy transport

Nature Physics volume 20, pages 1045–1046 (2024)Cite this article

Subjects

A superfluid is a macroscopic system with zero viscosity through which entropy is reversibly transported by waves. An unexpected transport phenomenon has now been observed between two superfluids, where irreversible entropy transport is enhanced by superfluidity.
