  • 实验测量了镀石蜡Rb池和石英玻璃Rb池中Rb原子自旋态寿命. 研究表明,镀石蜡Rb池的Rb原子自旋态寿命在温度T=50℃约为7 ms,而在同样温度的石英玻璃池中,Rb原子自旋态寿命仅为20 μs. 这为基于自旋的量子存储实验提供了很好的借鉴. 同时讨论了其他候选的材料来隔绝碱金属原子和容器壁的非弹性碰撞相互作用. 根据实验结果,我们认为H原子布于笼状结构内部的C60H60以及BN材料有较大的实用前景.
    We have measured the Rb atomic spin lifetime in both of paraffin-coated cell and glass cell. The experimental results shows that the lifetime of Rb atomic spin in paraffin-coated cell is about 7 ms at temperature T=50 ℃, while the data in glass cell is about 20 μs, which is useful for quantum memory experiments based on atomic spin. Meanwhile, we discuss other potential materials which can be used to eliminate the inelastic collisions between alkali metal atoms and walls. Based on some experimental data and investigation, we think that BN and C60H60 may be the candidates.
