Abstract

为在处于汗衫状态的 ultracold Na 和 K 原子之间的碰撞的有弹性的散布性质被调查。基于最近的理论、试验性的结果，改进混合潜力为 NaK 的汗衫 X1 g+ 地面状态被介绍。借助于 Numerov 和半古典作品方法，散布长度的 s 波浪的价值一因为汗衫状态是打算的分别地是 33.3757a0 和 37.9399a0。显著形状回声为 l = 出现为 X1 g+ 状态的 1 个部分波浪。另外，为 X1 g+ 状态散布生气的节，全部的生气的节和形状回声的精力位置的 s 波浪被讨论。

Elastic Scattering of Ultracold 23 Na and 39 K Atoms in the Singlet State

Hu Qiu-Bo, Zhang Yong-Sheng, Sun Jin-Feng

The elastic scattering properties for collisions between ultracold Na and K atoms in the singlet state are investigated. Based on the recent theoretical and experimental results, the improved hybrid potential is presented for the singlet X 1 Σ g + ground state of NaK. By means of the Numerov and semiclassical methods, the values of the s-wave scattering length a for the singlet state are calculated to be 33.3757 a 0 and 37.9399 a 0 , respectively. Pronounced shape resonances appear for the l = 1 partial wave for the X 1 Σ g + state. In addition, the s-wave scattering cross section, total cross section and energy positions of shape resonances for the X 1 Σ g + state are discussed.

Elastic Scattering of Sodium Atoms at Ultracold Temperatures

Jicai Zhang, Jinfeng Sun, Jiemin Wang

The calculations of the elastic scattering properties for collisions between two 23Na atoms at ultra-cold temperatures are reported and compared with experimental and theoretical results in the detail. We present a parametric model potential for the triplet molecular state of the 23Na molecule, and calculate the scattering length ɑ(subscript t) and the effective range r(subscript e) by using the semiclassical and Numerov methods, respectively. The shape resonances occur in the collisions at low energies, and resonance positions and widths are computed by Briet-Wigner formula. In addition, we also present other results that include differential cross sections at zero energy limit.

超冷极性分子具有长程电偶极相互作用与丰富的内部自由度，在多个前沿研究领域具有巨大的应用潜力。第一转动能态作为核心的旋转自由度，是实现分子量子态操控的首要选择，可以用来精确调控极性分子的长程相互作用强度，或者作为量子信息处理中的量子态。本文以超冷23Na40K分子为研究对象，开展了两个超精细基态对应的不同第一转动激发态能级结构的研究，并且实现了超冷分子在基态和第一转动激发态之间的相干操控。首先通过理论计算标定了第一转动态中的不同超精细能级以及基态到激发态跃迁频率随外磁场的变化，随后实验上通过测量基态分子损耗谱的方法确定了第一转动激发态的共振频率。结果表明，理论计算与实验数据呈现出高度一致性。进一步利用微波场驱动实现了分子在基态和第一转动激发态之间的拉比振荡。该研究为后续基于超冷极性分子第一转动态的研究提供了基础。
