Abstract
We present a scheme using a single four-level atom to entangle two mesoscopic mirrors. If the coupling between the cavity fields and the atom is suitable, then our study shows entanglement between the two movable mirrors, between the two-mode fields, and also between the mirror and the distant cavity mode. Because the energy difference between the two lowest levels of the four-level atom is not negligible, the entanglement of the mirrors as well as the squeezing spectrum of the output cavity fields display a splitting phenomenon. In the present scheme, only a single trapped atom is used, which sheds new light on the use of microscopic atomic coherence for the production of mesoscopic entanglement.
