Measuring the Superfluid Fraction of an Ultracold Atomic Gas
arXiv:0910.4767 · doi:10.1103/PhysRevLett.104.030401
Abstract
We propose a method to measure the superfluid fraction of an atomic gas. The method involves the use of a vector potential generated by optical beams with non-zero angular momentum to simulate uniform rotation. The induced change in angular momentum of the atomic gas can be measured spectroscopically. This allows a direct determination of the superfluid fraction.
