    "abstract": "We discuss the semiclassical limit of the entanglement for the class of\nclosed pure systems. By means of analytical and numerical calculations we\nobtain two main results: (i) the short-time entanglement does not depend on\nPlanck\u0027s constant and (ii) the long-time entanglement increases as more\nsemiclassical regimes are attained. On one hand, this result is in contrast\nwith the idea that the entanglement should be destroyed when the macroscopic\nlimit is reached. On the other hand, it emphasizes the role played by\ndecoherence in the process of emergence of the classical world. We also found\nthat, for Gaussian initial states, the entanglement dynamics may be described\nby an entirely classical entropy in the semiclassical limit.",
