超长程Rydberg分子的广义定域标架变换理论

Generalized local frame transformation theory for ultralong-range Rydberg molecules

P. Giannakeas, Matthew T. Eiles, F. Robicheaux, Jan-Michael Rost

摘要:

基于广义定域标架变换,建立了高激发态里德堡分子的详细理论框架。我们的方法避免了使用赝势,并产生体架反应矩阵的解析表达式。后者用于获得分子势能曲线,但同样可以用于光解离,光电离或其他过程。为了说明我们治疗的可靠性和准确性,我们考虑Rb $^*-$ Rb Rydberg分子,并将我们的治疗与最先进的替代方法进行比较。作为第二个应用程序,本形式主义是用来重新分析的Sr $^*-$ Sr分子的振动光谱,提供额外的物理洞察到他们的属性和我们的结果与相应的测量比较。

英文摘要:

A detailed theoretical framework for highly excited Rydberg molecules is developed based on the generalized local frame transformation. Our approach avoids the use of pseudopotentials and yields analytical expressions for the body-frame reaction matrix. The latter is used to obtain the molecular potential energy curves, but equally it can be employed for photodissociation, photoionization, or other processes. To illustrate the reliability and accuracy of our treatment we consider the Rb$^*-$Rb Rydberg molecule and compare our treatment with state-of-the-art alternative approaches. As a second application, the present formalism is used to re-analyze the vibrational spectra of Sr$^*-$Sr molecules, providing additional physical insight into their properties and a comparison of our results with corresponding measurements.
