I will first recall the Rabi and the related Jaynes-Cummings and Dicke

models and present the Rabi lattice (RLM) and the Jaynes-Cummings (JC)

lattice models. After a brief review of the JC model phase diagram, I

will present our work on the phase diagram of the RLM using mean field

and QMC simulations. We will map out the phase diagram and study the

role of the counter rotating terms and the conditions under which the JC

model becomes a good approximation for the RLM. I will also discuss our

work in progress on the phase diagram of Bose-Hubbard model coupled to a

single cavity mode (Dicke model) and compare with experimental results

(Esslinger's group).
