    "abstract": "We model collisionless collective conversion of a degenerate Fermi gas into\nbosonic molecules via a Feshbach resonance, treating the bosonic molecules as a\nclassical field and seeding the pairing amplitudes with random phases. A\ndynamical instability of the Fermi sea against association into molecules\ninitiates the conversion. The model qualitatively reproduces several\nexperimental observations {[Regal et al., Nature {\\bf 424}, 47 (2003)]}. We\npredict that the initial temperature of the Fermi gas sets the limit for the\nefficiency of atom-molecule conversion.",
