Rydberg atoms of ⁸⁷Rb in crossed electric and magnetic fields — •Manuel Kaiser, Jens Grimmel, Peter Zwissler, Lara Torralbo-Kampo, and József Fortágh — Center for Quantum Science, Physikalisches Institut, Universität Tübingen, Germany

External fields change the energy structure of Rydberg atoms drastically and can therefore be used to measure the fields or to manipulate the atoms but also disturb measurements if stray fields can not be compensated. Therefore precise knowledge of the Stark and Zeeman spectrum is of great interest.

We present measurements and numerical calculations of Stark and Zeeman shifts for Rydberg states of ⁸⁷Rb. We have extended our previous calculations [1] to a crossed electric and magnetic field situation taking into account the Stark and Zeeman structure as well as the transitions strength between all states in the EIT ladder scheme. We have performed high resolution measurements in various heated vapour cells being able to resolve the Motional Stark Effect in weak magnetic fields.
