We study the ground state cooling of a mechanical resonator in the membrane-in-the-middle (MIM) optomechanical system driven by only one drive field, including a continuous-wave, square-pulse, or Gaussian-pulse field. Details of the dynamical evolution of the phonon number under different conditions are presented, and the effect of system conditions on cooling is discussed. We show that the theoretical cooling limit of a single cavity with a single continuous-wave drive field can be broken with the MIM system. Even a one order lower cooling rate, such as $ ({n_{m,f}}/{n_{\rm th}}) \times ({\kappa _1}/{\gamma _m}) \sim 0.1 $, is possible with the combination of an appreciated damping rate, drive intensity, and duration of the Gaussian-pulse field.

通过单个驱动器对中间膜系统中的机械谐振器进行有效的基态冷却

我们研究仅由一个驱动场（包括连续波，方波或高斯脉冲场）驱动的中间膜（MIM）光学机械系统中机械谐振器的基态冷却。给出了在不同条件下声子数动态演化的细节，并讨论了系统条件对冷却的影响。我们表明，MIM系统可以打破具有单个连续波驱动场的单个腔的理论冷却极限。甚至$ 1（{n_ {m，f}} / {n _ {\ rm th}}）\ times（{\ kappa _1} / {\ gamma _m}）\ sim 0.1 $甚至更低的冷却速度。通过将阻尼率，驱动强度和高斯脉冲场的持续时间结合起来，这是可能的。
