The rapid development of micro- and nanomechanical oscillators in the past decade has led to the emergence of novel devices and sensors that are opening new frontiers in both applied and fundamental science. The potential of these devices is however affected by their increased sensitivity to external perturbations. Here we report a non-perturbative optomechanical stabilization technique and apply the method to stabilize a linear nanomechanical beam at its thermodynamic limit at room temperature. The reported ability to stabilize a nanomechanical oscillator to the thermodynamic limit can be extended to a variety of systems and increases the sensitivity range of nanomechanical sensors in both fundamental and applied studies.
在过去的十年中，微纳机械振荡器的快速发展催生了新型器件和传感器，为应用科学和基础科学开辟了新的前沿。然而，这些器件的潜力受到其对外界干扰敏感性增加的影响。在这里，我们报告了一种非微扰光机械稳定技术，并将该方法应用于在室温下将线性纳米机械梁稳定在其热力学极限。所报道的将纳米机械振荡器稳定在热力学极限的能力可以扩展到各种系统，并提高基础研究和应用研究中纳米机械传感器的灵敏度范围。
