We propose a quantum simulation of a two-level atom coupled to a single mode of the electromagnetic field in the ultrastrong coupling regime based upon resonant Raman transitions in an atom interacting with a high finesse optical cavity mode. We show by numerical simulation the possibility of realizing the scheme with a single rubidium atom, in which two hyperfine ground states make up the effective two-level system, and for cavity QED parameters that should be achievable with, for example, microtoroidal whispering-gallery-mode resonators. Our model takes account of dissipation, and we pay particular attention to observables that would be readily observable in the output from the system.
