Tweezer Arrays for Rydberg States in Erbium for Quantum Simulation — •Arno Trautmann1, Philipp Ilzhöfer1, Benedict Hochreiter1, Manfred J. Mark1,2, and Francesca Ferlaino1,2 — 1Institute for Quantum Optics and Quantum Information Innsbruck, Austria — 2University of Innsbruck, Austria
We present our design for a novel platform for quantum simulation based on erbium-Rydberg atoms in optical tweezers. Rydberg atoms are promising candidates for quantum simulation due to their extremely strong and long-range interactions, and have been applied already very successfully in alkali atoms. However, the simple electronic structure with only one valence electron limits the possible manipulation of Rydberg states, such as trapping, cooling or direct imaging. The extension to Rydberg states in multi-electron atoms is natural, and recently strontium and ytterbium have been studied. We plan to use erbium atoms, which have two valence electrons in their outer 6s shell and 12 electrons in an open, sub-merged, 4f shell. The properties of Rydberg states in such a complex system are not yet well understood and require intense spectroscopic effort. We here present our design for a new experiment dedicated to the study of these states in controllable arrays of optical tweezers.
