n粒子原子关联的光散射直接探测

Direct detection of n-particle atomic correlations via light scattering

L. Jin, M. Macovei, J. Evers

摘要:

研究了原子系综中n粒子原子关联的产生和直接探测。为此,我们研究了激光驱动的原子系综,其中偶极-偶极或里德伯-里德伯相互作用导致原子内部自由度之间形成相关性。我们表明,光散射可以用来将这些相关性的信息印在光上,并揭示了如何从散射光的统计特性中提取这些信息。作为主要结果,我们发现,在某些检测方向的观察允许直接和单独测量n粒子原子的相关性。作为补充,我们讨论了一种方法来实验确定感兴趣的检测位置。

英文摘要:

The creation and direct detection of n-particle atomic correlations in ensembles of atoms is investigated. For this, we study an ensemble of laser-driven atoms in which either a dipole-dipole or a Rydberg-Rydberg interaction leads to the formation of correlations between the internal degrees of freedom of the atom. We show that light scattering can be used to imprint information about these correlations onto light, and reveal how this information can be extracted from the statistical properties of the scattered light. As main result we find that observation in certain detection directions allows to directly and individually measure n-particle atomic correlations. Complementary, we discuss a method to experimentally determine the interesting detection positions.
