We have found an incorrect formula to estimate the root mean square (rms) amplitude of the molecular vibration in the molecular optomechanics systems reported by J. Liu et al. [Photon. Res.5, 450–456 (2017)PRHEIZ2327-912510.1364/PRJ.5.000450]. In contrast with common optomechanical systems, the equilibrium position for molecular optomechanics systems used in the letter cannot be achieved by the equipartition theorem. Here, we achieve the effective temperature of molecules and then provide a corrected formula for the estimation of the rms amplitude of molecular motion. Using defined effective temperature into our new formula, we show that the minimal measurable force is (F≈1.7×10−14 N), which it is 1 order bigger than the result of the main paper, and it is also in accordance with numerical calculation through the Lindblad master equation.

我们发现了一个错误的公式来估计 J. Liu 等人报道的分子光机械系统中分子振动的均方根 (rms) 幅度。[光子。Res.5, 450–456 (2017)PRHEIZ2327-912510.1364/PRJ.5.000450]。与普通的光机系统相比,信中使用的分子光机系统的平衡位置不能通过均分定理来实现。在这里,我们获得了分子的有效温度,然后提供了一个修正的公式来估计分子运动的均方根幅度。在我们的新公式中使用定义的有效温度,我们表明最小可测量力为(F≈1.7×10−14 N),比主要论文的结果大1个数量级,并且也符合数值通过 Lindblad 主方程计算。
