Fig. 4 (Color online) The emission spectrum $S(\Delta_{k})\omega_{ M}$ as a function of $\Delta_{k}/\omega_{ M}$ when the cavity field decay rate $\kappa$ takes different values $\kappa/\omega_{ M}=0.02$, $0.05$, $0.08$, and $0.15$. The initial state of the mechanical resonator is $|0\rangle_{b}$. Other parameters are given by $g_{1}/\omega_{ M}=0.8$ and $g_{2}/\omega_{ M}=0.05$.
