Observation of a quenched moment of inertia in a rotating strongly interacting Fermi gas
arXiv:0705.2782 · doi:10.1103/PhysRevLett.99.140401
Abstract
We make a model-independent measurement of the moment of inertia of a rotating, expanding strongly-interacting Fermi gas. Quenching of the moment of inertia is observed for energies both below and above the superfluid transition. This shows that a strongly interacting Fermi gas with angular momentum can support irrotational flow in both the superfluid and collisional normal fluid regimes.
