Measurements and numerical calculations of ⁸⁷Rb Rydberg Stark and Zeeman maps — •Jens Grimmel, Manuel Kaiser, Lara Torralbo-Campo, Markus Mack, Florian Karlewski, and József Fortágh — Physikalisches Institut der Universität Tübingen

Rydberg atoms are extremely sensitive to external electric and magnetic fields and consequently have a rich Stark and Zeeman spectrum. We present measurements and numerical calculations of Stark and Zeeman shifts for Rydberg states of ⁸⁷Rb. We have extended our previous calculations [1] to take into account the differential Zeeman shifts as well as the transition strength between all states in the EIT ladder scheme. We have also performed high precision measurements of Zeeman maps in a heated vapour cell with magnetic fields up to 10mT. Recently, we have implemented a new heatable microcell setup for measurements of Stark and Zeeman maps at different temperatures and atomic densities.
