(color online) (a) Entanglement En as a function of ϵ with different coupling V. The detuning frequency Δ / ω m = 1.01 . (b) En as a function of ϵ with different coupling V. The driving strength ϵ / ω m = 1.6 × 10 3 . Other parameters are g / ω m = 10 − 4 , κ / ω m = 10 − 2 , γ 1 / ω m = γ 2 / ω m = 10 − 5 , n th1 = n th2 = 0 .
