    "abstract": "By using numerical and semiclassical methods, we evaluate the quantum\nbreaking, or Ehrenfest time for a wave packet localized around classical\nequilibrium points of autonomous one-dimensional systems with polynomial\npotentials. We find that the Ehrenfest time diverges logarithmically with the\ninverse of the Planck constant whenever the equilibrium point is exponentially\nunstable. For stable equilibrium points, we have a power law divergence with\nexponent determined by the degree of the potential near the equilibrium point.",
