    "abstract": "We consider a model Hamiltonian describing the interaction of a single-mode\nradiation field with the atoms of a nonlinear medium, and study the dynamics of\nentanglement for specific non-entangled initial states of interest: namely,\nthose in which the field mode is initially in a Fock state, a coherent state,\nor a photon-added coherent state. The counterparts of near-revivals and\nfractional revivals are shown to be clearly identifiable in the entropy of\nentanglement. The ``overlap fidelity\u0027\u0027 of the system is another such indicator,\nand its behaviour corroborates that of the entropy of entanglement in the\nvicinity of near-revivals. The expectation values and higher moments of\nsuitable quadrature variables are also examined, with reference to possible\nsqueezing and higher-order squeezing.",
