单个囚禁原子的量子涨落:瞬态Rabi振荡和磁双稳

Quantum Fluctuations of a Single Trapped Atom: Transient Rabi Oscillations and Magnetic Bistability

H. Schadwinkel, V. Gomer, U. Reiter, B. Ueberholz, D. Meschede

摘要:

分离单个原子并监测其共振荧光是研究辐射与物质相互作用中量子效应的有力工具。在这里,我们提出了一个孤立的中性原子存储在磁光阱的量子动力学的观察。通过原子共振荧光中的光子关联,我们证明了与原子瞬态拉比振荡相对应的光子反聚束现象。通过对偏振敏感的光子关联,我们展示了一个新的解决量子涨落的例子:原子的自发磁取向。这些效应只能用单个原子观察到。

英文摘要:

Isolation of a single atomic particle and monitoring its resonance fluorescence is a powerful tool for studies of quantum effects in radiation-matter interaction. Here we present observations of quantum dynamics of an isolated neutral atom stored in a magneto-optical trap. By means of photon correlations in the atom's resonance fluorescence we demonstrate the well-known phenomenon of photon antibunching which corresponds to transient Rabi oscillations in the atom. Through polarization-sensitive photon correlations we show a novel example of resolved quantum fluctuations: spontaneous magnetic orientation of an atom. These effects can only be observed with a single atom.
