    "abstract": "We propose an experiment to measure the slow log(N) convergence to mean-field\ntheory (MFT) around a dynamical instability. Using a density matrix formalism,\nwe derive equations of motion which go beyond MFT and provide accurate\npredictions for the quantum break-time. The leading quantum corrections appear\nas decoherence of the reduced single-particle quantum state.",
