    "abstract": "We present a nonlinear decoherence model which models decoherence effect\ncaused by various decohereing sources in a quantum system through a nonlinear\ncoupling between the system and its environment, and apply it to investigating\ndecoherence in nonclassical motional states of a single trapped ion. We obtain\nan exactly analytic solution of the model and find very good agreement with\nexperimental results for the population decay rate of a single trapped ion\nobserved in the NIST experiments by Meekhof and coworkers (D. M. Meekhof, {\\it\net al.}, Phys. Rev. Lett. {\\bf 76}, 1796 (1996)).",
