摘要:

几个85 Rb原子被困在一个微米大小的磁光阱与高四极磁场梯度和原子的数量被精确控制通过抑制随机加载和损失事件通过实时反馈的磁场梯度。测得的单原子占据几率高达99%。五个原子也被困在高占领概率。本技术可用于制造确定性原子源。

英文摘要:

A few 85Rb atoms were trapped in a micron-size magneto-optical trap with a high quadrupole magnetic-field gradient and the number of atoms was precisely controlled by suppressing stochastic loading and loss events via real-time feedback on the magnetic field gradient. The measured occupation probability of single atom was as high as 99%. Atoms up to five were also trapped with high occupation probabilities. The present technique could be used to make a deterministic atom source.
