Contribution

It introduces a model for steady-state entanglement between a BEC and a nanomechanical resonator mediated by a laser field, emphasizing temperature effects.

Findings

Steady-state entanglement exists between BEC and resonator.

Entanglement is sensitive to temperature increases.

Laser field mediates the interaction effectively.

Abstract

We analyze the steady-state entanglement between Bose-Einstein condensate trapped inside an optical cavity with a moving end mirror (nanomechanical resonator) driven by a single mode laser. The quantized laser field mediates the interaction between the Bose-Einstein condensate and nanomechanical resonator. In particular, we study the influence of temperature on the entanglement of the coupled system, and note that the steady-state entanglement is fragile with respect to temperature.
