    "abstract": "We present the first scheme for producing and measuring an Abelian geometric\nphase shift in a three-level system where states are invariant under a\nnon-Abelian group. In contrast to existing experiments and proposals for\nexperiments, based on U(1)-invariant states, our scheme geodesically evolves\nU(2)-invariant states in a four-dimensional SU(3)/U(2) space and is physically\nrealized via a three-channel optical interferometer.",
