Photon phonon entanglement in coupled optomechanical arrays

TL;DR

This paper investigates photon-phonon entanglement in a coupled array of optomechanical cavities, demonstrating the presence of entanglement between optical and mechanical modes across the system.

Contribution

It introduces a model of coupled optomechanical arrays and analyzes the entanglement properties between optical and mechanical modes.

Findings

Intercavity photon-phonon entanglement is present in the system.

Entanglement depends on the coupling configuration and parameters.

The system exhibits complex entanglement dynamics across cavities.

Abstract

We consider an array of three optomechanical cavities coupled either reversibly or irreversibly to each other and calculate the amount of entanglement between the different optical and mechanical modes. We show the composite system exhibits intercavity photon-phonon entanglement.
