Realization of topological Thouless pumping in a synthetic Rydberg dimension — •Johannes Deiglmayr¹, Martin Trautmann¹, and Inti Sodemann Villadiego² — ¹Felix-Bloch Institute, Leipzig University, Linnéstraße 5, 04103 Leipzig, Germany — ²Institute for Theoretical Physics, Leipzig University, Brüderstraße 16, 04103 Leipzig, Germany

Synthetic dimensions provide the opportunity to investigate regimes outside those of more traditional quantum many-body platforms. Rydberg states of atoms are a particularly promising platform to engineer Hamiltonians in such synthetic dimensions due to the large number of states and the readily available technologies for manipulating their couplings and for detecting them.

We will present the realization of topological quantum pumping in a synthetic dimension by engineering a one-dimensional Rice-Mele chain within the Rydberg states of cesium atoms [1]. The Thouless protocols for topological pumping is implemented, and the adiabaticity of transport is investigated.
