    "abstract": "We investigate the behavior of N atoms resonantly coupled to a single\nelectromagnetic field mode sustained by a high quality cavity, containing a\nmesoscopic coherent field. We show with a simple effective hamiltonian model\nthat the strong coupling between the cavity and the atoms produces an\natom-field entangled state, involving N+1 nearly-coherent components slowly\nrotating at different paces in the phase plane. The periodic overlap of these\ncomponents results in a complex collapse and revival pattern for the Rabi\noscillation. We study the influence of decoherence due to the finite cavity\nquality factor. We propose a simple analytical model, based on the Monte Carlo\napproach to relaxation. We compare its predictions with exact calculations and\nshow that these interesting effects could realistically be observed on a two or\nthree atoms sample in a 15 photons field with circular Rydberg atoms and\nsuperconducting cavities.",
