Density plot of (a) \(E^{a\phi }_{N}\), (b) \(E^{m_1\phi }_{N}\), (c) \(E^{a m_1}_{N}\), (d) \(E^{m_1m_2}_{N}\) versus the normalized detuning \(\Delta _{m_1}/\omega _{\phi }\) and \(\Delta _{m_2}/\omega _{\phi }\). Here we have taken effective cavity detuning \(\Delta _a^{\prime }=\omega _{\phi }\) for all cases.
