(color online) (a) and (c) Effective frequency ω_eff and effective dissipation rate γ_eff as a function of driving strength ϵ. The detuning frequency Δ / ω m = 1.01 . (b) and (d) ω_eff and γ_eff as a function of detuning frequency Δ. The driving strength ϵ / ω m = 1.5 × 10 3 . Other parameters are g / ω m = 10 − 4 , κ / ω m = 10 − 2 , and γ 1 / ω m = 10 − 5 .
