论文摘要
我们报告了对在高真空中光学陷阱中悬浮的纳米颗粒自由度的所有翻译和角度自由度的强烈冷却和定向控制。使用高技巧光学腔内的连贯的椭圆散射来实现由光学镊子悬浮的纳米颗粒的所有六个自由度的动作冷却和控制。达到了100美元$ K范围的转化温度，而在自由度的自由度下，温度低至5 MK。这项工作代表了控制悬浮粒子的所有可观察到的自由度的重要里程碑，并在量子科学和单个分离的纳米颗粒的研究中打开了未来的应用。
We report on strong cooling and orientational control of all translational and angular degrees of freedom of a nanoparticle levitated in an optical trap in high vacuum. The motional cooling and control of all six degrees of freedom of a nanoparticle levitated by an optical tweezer is accomplished using coherent elliptic scattering within a high finesse optical cavity. Translational temperatures in the 100 $μ$K range were reached while temperatures as low as 5 mK were attained in the librational degrees of freedom. This work represents an important milestone in controlling all observable degrees of freedom of a levitated particle and opens up future applications in quantum science and the study of single isolated nanoparticles.
