    "abstract": "We show that the quantum fidelity is accessible to cold atom experiments for\na large class of evolutions in periodical potentials, properly taking into\naccount the experimental initial conditions of the atomic ensemble. We prove\nanalytically that, at the fundamental quantum resonances of the atom-optics\nkicked rotor, the fidelity saturates at a constant, time-independent value\nafter a small number of kicks. The latter saturation arises from the bulk of\nthe atomic ensemble, whilst for the resonantly accelerated atoms the fidelity\nis predicted to decay slowly according to a power law.",
