论文摘要
这项工作是在观察Efimov和Bose Polaron物理学的前景中的动机，这项工作调查了$^{7} \ text {li} $和$^{133} \ {133} \ text {cs} $之间的磁性Feshbach共振。使用Pires等人的模型在1高斯水平上预测共振。 [物理。 Rev. A，90，012710]从$^{6} \ text {li} $和$^{133} \ text {cs} $之间的共振的实验观察中获得。发现在实用磁场强度范围内的一些共鸣可以用来调整$^{7} \ text {li} $和$^{133} \ text {cs} $原子之间的散射长度。讨论了观察Efimov和Bose Polaron物理学的机会。
Motivated by the prospect of observing Efimov and Bose polaron physics in ultracold mixtures of bosonic atoms with large mass imbalance, this work investigates the magnetic Feshbach resonances between $^{7}\text{Li}$ and $^{133}\text{Cs}$. The resonances are predicted at the 1 gauss level using the model of Pires et al. [Phys. Rev. A, 90, 012710] obtained from experimental observations of resonances between $^{6}\text{Li}$ and $^{133}\text{Cs}$. It is found that a few resonances in a practical range of magnetic field intensity could be used to tune the scattering length between $^{7}\text{Li}$ and $^{133}\text{Cs}$ atoms. Opportunities for observing Efimov and Bose polaron physics are discussed.
