STATIONARY ENTANGLEMENT DYNAMICS IN A HYBRID OPTO-ELECTRO-MECHANICAL SYSTEM

In this paper, we investigate the stationary entanglement dynamics be-tween the neighboring subsystems using an opto-electro-mechanical system, in which the mechanical resonator simultaneously coupled to both microwave and optical cavi-ties through the plate of capacitor coupling process. Under the linearization approxima-tion, the dynamics of the entanglement is quantifying by using logarithmic negativity. Our numerical simulation exhibits a sharing bipartite entanglement with optical cavity-mechanical, microwave cavity-mechanical, and optical cavity-microwave modes. We further show that there is an entanglement between the optical cavity and microwave modes despite the lack of direct coupling with these modes and optical cavity. Thus, an effective interaction between the optical cavity-microwave cavity mediated by the mechanical resonator, and therefore microwave entanglement is efficiently generated. Such a hybrid electro-optomechanics system can serve as a promising platform to con-trol the follow of light in the Nano-Photonic structure and framework for the optome-chanical information transfer between the microwave and optical cavities.
