    "abstract": "The advantages of light and matter-wave Sagnac interferometers -- large area\non one hand and high rotational sensitivity per unit area on the other -- can\nbe combined utilizing ultra-slow light in cold atomic gases. While a\ngroup-velocity reduction alone does not affect the Sagnac phase shift, the\nassociated momentum transfer from light to atoms generates a coherent\nmatter-wave component which gives rise to a substantially enhanced rotational\nsignal. It is shown that matter-wave sensitivity in a large-area interferometer\ncan be achieved if an optically dense vapor at sub-recoil temperatures is used.\nAlready a noticeable enhancement of the Sagnac phase shift is possible however\nwith much less cooling requirements.",
