Abstract: (1795 Views)
In this paper, entanglement dynamics in a quadripartite optomechanical system is investigated. The system contains two two-level atoms such that one atom interacts with cavity modes and the other is out of the cavity with no interaction. With the assumption that one of the cavity mirrors is in motion, entanglement is evaluated by negativity. The results show that among the considered subsystem, only two atoms are entangled, which can be controlled by the optomechanical coupling.
