Construction of a versatile Rydberg atom platform — •Aaron Thielmann, Sven Schmidt, Suthep Pomjaksilp, Thomas Niederprüm, and Herwig Ott — Department of Physics and research center OPTIMAS, RPTU Kaiserslautern-Landau

In recent years, atomic arrays emerged as a ground-breaking platform in quantum physics. These setups do not only feature single-atom control, additionally exciting addressable atoms to Rydberg states introduces further possibilities to study physical problems in different geometric configurations.

We plan to realize arbitrarily arranged two-dimensional arrays with up to 100 lattice sites, each of them containing one or a few atoms. The arrays are holographically generated by an SLM in combination with a 1064 nm YAG-laser. Via a two-photon Rydberg transition, we collectively excite the atoms to Rydberg states. Due to the long-range character of the resulting Rydberg interactions, an interaction of the atoms in and between lattice sites is also intrinsically given. This setup is a prime candidate to investigate both topological systems of single atoms as well as effects arising from many-body properties in a controlled manner.

Adding controlled microwave transitions between different Rydberg states and the incorporation of a second atomic species open up possibilities to study even more complex physical systems in future research.
