Figure 8From: Simultaneous cooling and synchronization of the mechanical and the radio-frequency resonators via voltage modulationThe time evolution of mean phonon number \(n_{f}^{i}\) and quantum synchronization \(S_{c}\) with the voltage modulation (\(\eta =1\)). The pink shaded region signifies the ground state cooling for \(N<1\). 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. 3Back to article page
