Theoretical Calculations of the Dynamic Polarizabilites and the Tune-Out Wave Length for H Atom

本文给出了稳定变分方法计算单价原子的动态极化率的理论方法,在此基础上,自主开发了计算程序。利用该程序,以氢原子为例,计算了不同频率下氢原子基态的动态极化率。本文计算结果与文献中Green函数法的结果进行了比较,具有很好的一致性。分析了稳定变分法的收敛性,并利用计算的动态极化率进一步确定了相应的tune-out波长。

The theoretical method for calculating the dynamic polarizability of monovalent atoms by the variationally stable procedure is given. On this basis, the calculation program is independently developed by us. As an application, the dynamic polarizabilities at different frequencies are calculated with hydrogen atoms as an example, by this program. The calculation results are compared with the Green function data in the literature, with good consistency. The convergence of the variationally stable procedure is analyzed, and the corresponding tune-out wavelength is further determined by using the polarizability calculated in the present work.
