论文摘要
光与原子之间的相互作用在原子能水平上引起扰动，称为轻移。这些轻班是原子钟中不准确的关键来源，也可能使其精度恶化。我们介绍了基于$ 5S_ {1/2} $ - $ 5D_ {5/2} $在Rubidium-87的过渡范围770 nm至800 nm的$ 5S_ {1/2} $ - $ 5D_ {5/2} $的研究研究，以针对两光原子时钟的相关动态极化。我们确定在此范围内的魔术波长的实验和理论值，以及$ 5P_ {3/2} $ - $ 5D_ {5/2} $ transition的电偶极子（E1）矩阵元素。我们在$ 5P_ {3/2} $ - $ 5D_ {5/2} $共振的附近找到776.179（5）（5）（实验）和776.21 nm（理论）的魔术波长（理论上） （理论）。这些值解决了理论与实验之间的先前差异。
The interaction between light and an atom causes perturbations in the atom's energy levels, known as the light-shift. These light-shifts are a key source of inaccuracy in atomic clocks, and can also deteriorate their precision. We present a study of light-shifts and associated dynamic polarizabilities for a two-photon atomic clock based on the $5S_{1/2}$-$5D_{5/2}$ transition in rubidium-87 over the range 770 nm to 800 nm. We determine experimental and theoretical values for a magic wavelength in this range and the electric dipole (E1) matrix element for the $5P_{3/2}$-$5D_{5/2}$ transition. We find a magic wavelength of 776.179(5) nm (experimental) and 776.21 nm (theoretical) in the vicinity of the $5P_{3/2}$-$5D_{5/2}$ resonance, and the corresponding reduced E1 matrix element 1.80(6) $ea_0$ (experimental) and 1.96(15) $ea_0$ (theoretical). These values resolve a previous discrepancy between theory and experiment.
