摘要:

研究了与高精细度光腔场强耦合的单个囚禁原子在轴向运动基态的局域化。轴向运动的原子通过红色振动边带上的相干拉曼跃迁冷却。利用腔QED中强耦合实现的一种有效的状态探测方案被用来记录拉曼光谱,从拉曼光谱中推断原子的运动状态。我们发现零点能为13 uK的轴向势的最低振动能级以概率P0~0.95被占据。

英文摘要:

Localization to the ground state of axial motion is demonstrated for a single, trapped atom strongly coupled to the field of a high finesse optical resonator. The axial atomic motion is cooled by way of coherent Raman transitions on the red vibrational sideband. An efficient state detection scheme enabled by strong coupling in cavity QED is used to record the Raman spectrum, from which the state of atomic motion is inferred. We find that the lowest vibrational level of the axial potential with zero-point energy 13uK is occupied with probability P0~0.95.
