    "abstract": "The light--matter-wave Sagnac interferometer based on ultra-slow light\nproposed recently in (Phys. Rev. Lett. 92, 253201 (2004)) is analyzed in\ndetail. In particular the effect of confining potentials is examined and it is\nshown that the ultra-slow light attains a rotational phase shift equivalent to\nthat of a matter wave, if and only if the coherence transfer from light to\natoms associated with slow light is associated with a momentum transfer and if\nan ultra-cold gas in a ring trap is used. The quantum sensitivity limit of the\nSagnac interferometer is determined and the minimum detectable rotation rate\ncalculated. It is shown that the slow-light interferometer allows for a\nsignificantly higher signal-to-noise ratio as possible in current matter-wave\ngyroscopes.",
