Exchange and core-polarization effects on Rydberg-transition electric-dipole matrix elements in Rb and Cs

Yu Shi-Cheng, Zhen-Xiang Zhong, Cheng-Bin Li

Microwave electric-field measurements with Rydberg atoms require accurate Rydberg-transition electric-dipole matrix elements. We calculate these matrix elements for Rb and Cs using…
