Title: Phase Transition in the two-photons Dicke Model

We present preliminary results on the study of the two-photon Dicke model in the Ultrastrong Coupling Regime. A mean field analysis shows the existence of a phase transition, which leads the system into a phase characterized by non-trivial spin and field excitations. We also discuss the possibility of a experimental implementation in trapped ions, using reservoir engineering.
