- Abstract summary: We show a strong spin-motion coupling emerging from the large variation of the interaction potential over the wavefunction spread.
We propose a novel approach to tune arbitrarily the strength of the spin-motion coupling relative to the motional energy scale set by trapping potentials.

- Abstract: Rydberg atoms in optical lattices and tweezers is now a well established
platform for simulating quantum spin systems. However, the role of the atoms'
spatial wavefunction has not been examined in detail experimentally. Here, we
show a strong spin-motion coupling emerging from the large variation of the
interaction potential over the wavefunction spread. We observe its clear
signature on the ultrafast, out-of-equilibrium, many-body dynamics of atoms
excited to a Rydberg S state from an unity-filling atomic Mott-insulator. We
also propose a novel approach to tune arbitrarily the strength of the
spin-motion coupling relative to the motional energy scale set by trapping
potentials. Our work provides a new direction for exploring the dynamics of
strongly-correlated quantum systems by adding the motional degree of freedom to
the Rydberg simulation toolbox.
