Moment of Inertia and Superfluidity of a Trapped Bose Gas
arXiv:cond-mat/9509166 · doi:10.1103/PhysRevLett.76.1405
Abstract
The temperature dependence of the moment of inertia of a dilute Bose gas confined in a harmonic trap is determined. Deviations from the rigid value, due to the occurrence of Bose-Einstein condensation, reveal the superfluid behaviour of the system. In the noninteracting gas these deviations become important at temperatures of the order of . The role of interactions is also discussed.
