    "abstract": "We discuss the ground state entanglement of a bi-partite system, composed by\na qubit strongly interacting with an oscillator mode, as a function of the\ncoupling strenght, the transition frequency and the level asymmetry of the\nqubit. This is done in the adiabatic regime in which the time evolution of the\nqubit is much faster than the oscillator one. Within the adiabatic\napproximation, we obtain a complete characterization of the ground state\nproperties of the system and of its entanglement content.",
