Abstract
A scheme to generate stationary entanglement in a Fabry-Perot cavity with two-level atoms is proposed in the current paper. The mechanism through which radiation pressure can generate steady-state entanglement is also presented. Moreover, the bipartite entanglement in the field-mirror subsystem is quantified. Logarithmic negativity, which characterizes the entanglement between the two systems, is found to increase from 0.27 to 0.32 with the help of the atoms. Surprisingly, such macroscopic entanglement persists for environment temperatures of about 25 K in this system.
