Phase diagram of the system stability in the P-κ plane in (a) and (c), and of the LC frequency shift \(\omega _{\mathrm{lc}}^{\prime }/\omega _{\mathrm{lc}}\) in (b) and (d) without voltage modulation (\(\eta =0\)). Here we have set \(\omega _{0}=2\pi \times 10^{6}\text{ Hz}\), \(\Delta =\omega _{0}\), \(g_{1}/\omega _{0}=3\times 10^{-4}\), \(g_{2}/\omega _{0}=5\times 10^{-4}\), \(V_{\mathrm{DC}}/\omega _{\mathrm{lc}}=15\), \(\gamma _{m}/\omega _{0}=\gamma _{\mathrm{lc}}/\omega _{0}=10^{-6}\), \(T=100\text{ mK}\), and driving field wavelength \(\lambda =1550\text{ nm}\). \(\omega _{\mathrm{lc}}=\omega _{0}\) in (a) and (b), \(\omega _{\mathrm{lc}}/\omega _{0}=10\) in (c) and (d)
