(color online) (a) The optomechanical system is composed of an optomechanical cavity and a variable capacitor. The voltage U(t) on the capacitor is supplied by a voltage waveform generator. An ensemble of N identical Λ-type three-level atoms is trapped inside the cavity. (b) The level structure of the i-th atom coupling to the probe (|b⟩ and |a⟩) and cavity (|c⟩ and |a⟩) fields. γ1 and γ2 are the decay rates from |a⟩ to |b⟩ and |c⟩, respectively. The detunings are Δp = ωab − ωp and δ = ωac − ωc.
