    "abstract": "Intrinsic decoherence in the thermodynamic limit is shown for a large class\nof many-body quantum systems in the unitary evolution in NMR and cavity QED.\nThe effect largely depends on the inability of the system to recover the\nphases. Gaussian decaying in time of the fidelity is proved for spin systems\nand radiation-matter interaction.",
