    "abstract": "A simple model allows us to study the nonclassical behavior of slowly moving\natoms interacting with a quantized field. Atom and field become entangled and\ntheir joint state can be identified as a mesoscopic \"Schroedinger-cat\". By\nintroducing appropriate observables for atom and field and by analyzing\ncorrelations between them based on a Bell-type inequality we can show the\ncorresponding nonclassical behavior.",
