The effective temperature \(T_{\mathrm{{eff}}}\) (K) and quantum synchronization \(S_{c}\) of mechanical and rf resonators as a function of the decay rate of cavity mode κ without the voltage modulation (\(\eta =0\)). Here we set \(\omega _{\mathrm{lc}}=\omega _{0}\) in (a), and \(\omega _{\mathrm{lc}}/\omega _{0}=10\) in (b). The other parameters are the same as in Fig. 3
