    "abstract": "We show how an ion trap, configured for the coherent manipulation of external\nand internal quantum states, can be used to simulate the irreversible dynamics\nof a collective angular momentum model known as the Dicke model. In the special\ncase of two ions, we show that entanglement is created in the coherently driven\nsteady state with linear driving. For the case of more than two ions we\ncalculate the entanglement between two ions in the steady state of the Dicke\nmodel by tracing over all the other ions. The entanglement in the steady state\nis a maximum for the parameter values corresponding roughly to a bifurcation of\na fixed point in the corresponding semiclassical dynamics. We conjecture that\nthis is a general mechanism for entanglement creation in driven dissipative\nquantum systems.",
