    "abstract": "he dynamical properties of quantum entanglement in a time-dependent\nthree-level-trapped ion interacting with a laser field are studied in terms of\nthe reduced-density linear entropy considering two specific initial states of\nthe field. Allowing the instantaneous position of the center-of-mass motion of\nthe ion to be explicitly time-dependent, it is shown that either sudden death\nof entanglement or survivability of quantum entanglement can be obtained with a\nspecific choice of the initial state parameters. The difference in evolution\npicture corresponding to the multi-quanta processes is discussed.",
