    "abstract": "We discuss the creation of many-particle entanglement in an ion trap where\nall ions are simultaneously coupled to bichromatic laser fields. It is shown\nthat in a time-averaged, coarse-grained picture the system can be mapped onto a\nspin ensemble with controllable collective interactions. An adiabatic change of\nlaser parameters allows a transfer from separable to entangled eigenstates of\nthe many-particle Hamiltonian. Of particular interest is a transition in the\nground state which in some cases corresponds to a quantum phase transition. The\ninfluence of decoherence mechanisms can be substantially reduced if at all\ntimes a sufficiently large energy gap between the ground state and the first\nexcited state is maintained.",
