Revisiting Joule-expansion experiments with a quantum gas
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 both cooling and heating effects, which arise, respectively, due to quantum statistics and inter-...

| description | 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 both
cooling and heating effects, which arise, respectively, due to quantum
statistics and inter-particle interactions. Our observations are reproduced in
numerical calculations within the Hartree-Fock approximation. |
