Entanglements in a coupled cavity–array with one oscillating end-mirror |
Plot of the logarithmic negativities (a) and (b) versus the environment temperature when Δ 1 = − ωm , Δ 2 = ωm . The solid, dashed, and dash–dotted lines are corresponding to different coupling strengths J = 0.6 ωm , 0.8 ωm , and ω m , respectively. |
