    "abstract": "We show that the physical system consisting of trapped ions interacting with\nlasers may undergo a rich variety of quantum phase transitions. By changing the\nlaser intensities and polarizations the dynamics of the internal states of the\nions can be controlled, in such a way that an Ising or Heisenberg-like\ninteraction is induced between effective spins. Our scheme allows us to build\nan analogue quantum simulator of spin systems with trapped ions, and observe\nand analyze quantum phase transitions with unprecedent opportunities for the\nmeasurement and manipulation of spins.",
