The steady state mean photon number in the cavity for no linear driving.The steady state mean photon number in the cavity for no coherent driving$ϵ=0$as a function of the parametric pump magnitude κ and the detuningΔ. The corresponding semi-classical fixed points plotted inFigure 2 showed bi-stability for negative detuning$\Delta <0$which does not occur in the quantum steady state. Time units are chosen so that$\gamma =1$and $\chi =0.25$.
