Joule expansion of a quantum gas
arXiv:2410.24217 · doi:10.1103/PhysRevResearch.7.L022048
Abstract
We revisit the classic Joule-expansion experiments, now with a quantum-degenerate atomic Bose gas. In contrast to the classical-gas experiments, where no temperature change was measured, here we observe and quantitatively explain both cooling and heating effects, which arise, respectively, due to quantum statistics and inter-particle interactions.
