单原子在微腔中的纳米定位

Nano Positioning of Single Atoms in a Micro Cavity

Stefan Nussmann, Markus Hijlkema, Bernhard Weber, Felix Rohde, Gerhard Rempe, Axel Kuhn

摘要:

单个原子与高精细光学腔的耦合是使用驻波偶极力阱精确控制和调节的,这对强原子-腔耦合是一个挑战。超冷铷原子首先被加载到腔中心的偶极阱的势能极小值中。然后我们把陷阱当作一条传送带,垂直于空腔轴线运动。这使我们能够重复地将原子移出和移回腔模,重新定位精度为135 nm。这使得可以通过腔选择性地寻址一串原子中的一个原子,或者同时将两个精确分离的原子耦合到腔的较高模式。

英文摘要:

The coupling of individual atoms to a high-finesse optical cavity is precisely controlled and adjusted using a standing-wave dipole-force trap, a challenge for strong atom-cavity coupling. Ultracold Rubidium atoms are first loaded into potential minima of the dipole trap in the center of the cavity. Then we use the trap as a conveyor belt that we set into motion perpendicular to the cavity axis. This allows us to repetitively move atoms out of and back into the cavity mode with a repositioning precision of 135 nm. This makes possible to either selectively address one atom of a string of atoms by the cavity, or to simultaneously couple two precisely separated atoms to a higher mode of the cavity.
