Addressing Rydberg s- and p-states in optical tweezers — •Roxana Wedowski, Ludwig Müller, Lea-Marina Steinert, Philip Osterholz, Arno Trautmann, and Christian Gross — Eberhard Karls Universität, Tübingen, Germany

Rydberg atom-based quantum simulators offer unique capabilities to implement strongly correlated many-body phenomena. An experimental system with single potassium-39 atoms placed in 2D arrays of optical tweezers allows us to study renowned models in spin physics, such as XYZ-type spin interactions. So far, this has been realized by off-resonant coupling via a single photon transition to Rydberg states. Here, we present an upgrade to the UV Laser system for the one photon excitation by elimination of limiting factors like phase noise. Additionally, a two-photon excitation scheme is implemented offering increased tunability. The flexible design of the simulated Hamiltonian, combined with the geometrical versatility of the system, is expected to reveal exciting prospects for the implementation of quantum magnets and nonlinear enhanced detection.
