00925njm 22002777a 4500 dc Bermúdez Carballo, Alejandro author Porras Torres, Diego author Martín-Delgado Alcántara, Miguel Ángel author 2009-06 We propose and theoretically analyze an experimental configuration in which lasers induce three-spin interactions between trapped ions. By properly choosing the intensities and frequencies of the lasers, three-spin couplings may be dominant or comparable to two-spin terms and magnetic fields. In this way, trapped ions can be used to study exotic quantum phases which do not have a counterpart in nature. We study the conditions for the validity of the effective three-spin Hamiltonian and predict qualitatively the quantum phase diagram of the system. 1050-2947 10.1103/PhysRevA.79.060303 https://hdl.handle.net/20.500.14352/42805 http://doi.org/10.1103/PhysRevA.79.060303 https://journals.aps.org Competing many-body interactions in systems of trapped ions
