    "abstract": "It is shown that, through a super-radiant Rayleigh scattering, a strong far\noff-resonant pump laser applied to a Bose-Einstein condensates(BEC) can induce\na non-demolition coupling of the many-mode quantized vacuum field to the BEC.\nThis effective interaction will force the total system of the BEC plus the\nlight field to evolve from a factorized initial state to an ideal entangled\nstate and thus result in the quantum decoherence in the BEC. Since the\neffective coupling coefficients are mainly determined by the Rabi frequency of\nthe pump laser, the quantum decoherence process can be controlled by adjusting\nthe intensity of the pump laser. To study the physical influence of decoherence\non the BEC, we investigate how the coherent tunneling of BEC in a\nwell-separated tight double wall is suppressed by the effectively-entangled\nvacuum modes.",
