论文摘要
保罗陷阱中带电的介电纳米颗粒的所有三个运动模式都通过直接反馈对几个MK的温度进行冷却。我们测试两种方法，一种基于电力，另一种是基于光学的。对于这两种方法，我们都发现了类似的冷却效率。两种反馈力的冷却是反馈参数，背景压力和粒子位置的函数的特征。
All three motional modes of a charged dielectric nanoparticle in a Paul trap are cooled by direct feedback to temperatures of a few mK. We test two methods, one based on electrical forces and the other on optical forces; for both methods, we find similar cooling efficiencies. Cooling is characterized for both feedback forces as a function of feedback parameters, background pressure, and the particle's position.
