(a), the effect of the optomechanical coupling strength ratio (A/B) and the strength of frequency sweeping field β/ωm, α/ωm = 0.15, Δ/ωm = −1. (b), the effect of the optomechanical coupling strength ratio (A/B) and cavity detuning Δ/ωm, α/ωm = 0.15, β/ωm = 0.05. (c), a no-chirped pulse scheme, to compares with (b). (d) and (e), the strength of frequency sweeping field β/ωm and cavity detuning Δ/ωm to the phonon number 〈nosc〉 = 〈δb†δb〉, A = 0, α/ωm = 0.15. For all of the plots, the time is set ωmt = 70, B = 2 * 10−4, γ/ωm = 10−6, κ/ωm = 0.3, Nth = 50, 〈a(0)〉 = 200, ωmt0 = 30.
