(a) Plot of the logarithmic negativity E mc versus the environment temperature. The red-dot-dashed, solid, blue-dashed curves refer to P = 1 mW, 5 mW, 10 mW, respectively. (b) Plot of the logarithmic negativity E mm versus the environment temperature. The red-dot-dashed, solid, blue-dashed curves refer to P = 6 mW, 8 mW, 10 mW, respectively. The other parameters are λ = 2 πc / ω 0 = 1064 nm, ω m = 2 π × 107 Hz, κ = π × 107 Hz, γ m1 = γ m2 = π × 400 Hz, L = 6 mm, m = 12 ng and we set the detuning and the angle are Δ 0 = 2 π × 107 Hz, and β = π /3, respectively.
