    "abstract": "We show that high squeezing and entanglement can be generated at the output\nof a cavity containing atoms interacting with two fields in a Coherent\nPopulation Trapping situation, on account of a non-linear Faraday effect\nexperienced by the fields close to a dark-state resonance in a cavity.\nMoreover, the cavity provides a feedback mechanism allowing to reduce the\nquantum fluctuations of the ground state spin, resulting in strong steady state\nspin-squeezing.",
