The coupling of a levitated submicron particle and an optical cavity field promises access to a unique parameter regime both for macroscopic quantum experiments and for high-precision force sensing. We report a demonstration of such controlled interactions by cavity cooling the center-of-mass motion of an optically trapped submicron particle. This paves the way for a light-matter interface that can enable room-temperature quantum experiments with mesoscopic mechanical systems.
悬浮亚微米粒子与光腔场的耦合有望为宏观量子实验和高精度力传感提供独特的参数范围。我们通过腔冷却光捕获的亚微米粒子的质心运动来演示这种受控相互作用。这为实现可以在室温下进行介观机械系统量子实验的光物质接口铺平了道路。
