    "abstract": "We present a detailed study of how phase-sensitive feedback schemes can be\nused to improve the performance of optomechanical devices. Considering the case\nof a cavity mode coupled to an oscillating mirror by the radiation pressure, we\nshow how feedback can be used to reduce the position noise spectrum of the\nmirror, cool it to its quantum ground state, or achieve position squeezing.\nThen, we show that even though feedback is not able to improve the sensitivity\nof stationary position spectral measurements, it is possible to design a\nnonstationary strategy able to increase this sensitivity.",
