Figure 1

(Color online) (a) The cavity is driven by a laser at frequency ${\omega }_l$ and the moving mirror at frequency ${\omega }_m$ scatters photons on the two sidebands at frequency ${\omega }_l\pm {\omega }_m$. (b) If the cavity with frequency ${\omega }_c$ and bandwidth $\kappa$ is put into resonance with the anti-Stokes sideband (blue), outgoing cavity photons cool the mirror vibrational mode. If the atoms are off-resonance with the cavity but resonantly coupled to the red sideband, an entangled tripartite atom-field-mirror system emerges.Reuse & Permissions

Figure 2

(Color online) (a) Logarithmic negativity of the mirror-field subsystem versus the normalized cavity detuning in the absence of the atoms. Entanglement is maximized around the optimal cooling regime (shown in the inset), namely around $\Delta \simeq {\omega }_m$ (see text for the other parameter values). (b) Logarithmic negativity for the three bipartite entanglements as a function of the normalized atomic detuning (see text for the value of atomic parameters). At ${\Delta }_a=-{\omega }_m$, a decrease in the mirror-field ($i$, blue line) entanglement is associated with an increase of the mirror-atoms ($ii$, red line) and atoms-field ($iii$, green line) entanglement. (c) Same as in (b) but for the larger temperature $T=5T_0$. (d) Temperature robustness of mirror-atoms entanglement up to $40T_0$ $\left(24\mathrm{K}\right)$.Reuse & Permissions
