Investigation of Rydberg atom interactions by observing electromagnetically induced transparency spectra — •Markus Mack, Florian Karlewski, Helge Hattermann, Peter Federsel, Simone Höckh, Florian Jessen, Daniel Cano, and József Fortágh — Physikalisches Institut, Eberhard-Karls-Universität Tübingen

Rydberg atoms stand out due to their high polarizability which makes them highly sensitive to electric fields and increases many-body interactions.

We determined the binding energy of the 87Rb isotope by extrapolating our recent results for excitation energies of optically accessible Rydberg states.

The combination of measurements of the stark shifts of these Rydberg levels close to a metallic surface and calculated Stark maps provides information concerning the dipole field of any atoms which are adsorbed to the surface.

All Rydberg states and their energy shifts were detected by observing electromagnetically induced transparency.
