    "abstract": "A simple model of a two-mode non-resonant parametric amplifier is studied\nwith special regard to non-classical features such as revivals and squeezing.\nThe methods used apply for an arbitrary pump parameter. Detailed analytical and\nexplicit expressions are given when the coupling of the two modes has an\nharmonic time-dependence. Despite its simplicity the model exhibits a very\nbroad range of intricate physical effects. We show that quantum revivals are\npossible for a broad continuous range of physical parameters in the case of\ninitial Fock states. For coherent states we find that such revivals are\npossible only for certain discrete rational number combinations of the ratio of\nfrequency detuning and pump parameters. Correlation effects are shown to be\nvery sensitive to the initial state of the system.",
