    "abstract": "Using the Calogero-Moser model and the Nakamura equations for a multi-partite\nquantum system, we prove an inequality between the mean bi-partite entanglement\nrate of change under the variation of a critical parameter and the\nlevel-curvature. This provides an upper bound for the rate of production or\ndistraction of entanglement induced dynamically. We then investigate the\ndependence of the upper bound on the degree of chaos of the system, which in\nturn, through the inequality, gives a measure of the stability of the entangled\nstate. Our analytical results are supported with extensive numerical\ncalculations.",
