Semi-classical steady states of the microwave system for different regionsof the phase diagram. Semi-classical steady states of the microwavesystem for different regions of the ‘phase diagram’ inFigure 3. These eight plots show thesemi-classical fixed points that correspond to the parameters of the eightblack crosses in Figure 3. Specifically theseparameter values, fro left to right, are: ( κ , Δ )=(3,10),(3.25,10),(3.5,10), and (3.75,10). The coloursindicate stability; the green circle markers are stable fixed points, and thered cross markers are unstable fixed points. All fixed points in the sameregions of parameter space are very similar qualitatively. These semi-classicalfixed points can be compared with the quantum steady state Wigner functions forthe same set of parameters in Figure 7.
