Coherent facilitation dynamics in Rydberg atomic lattice quantum simulators — •Paolo Pietro Mazza1, Richard Schmidt2,3, and Igor Lesanovsky1,41Institute of Theoretical physics, University of Tübingen, Auf der Morgenstelle 14, 72076 Tübingen, Germany — 2Max-Planck-Institute of Quantum Optics, Hans-Kopfermann-Strasse, 1, 85748 Garching, Germany — 3Munich Center for Quantum Science and Technology (MCQST), Schellingstr. 4, 80799 München, Germany — 4School of Physics and Astronomy and Centre for the Mathematics and Theoretical Physics of Quantum Non-Equilibrium Systems, The University of Nottingham, Nottingham, NG7 2RD, United Kingdom

The possibility to precisely control many-body systems at the quantum level has opened the era of quantum simulators. Rydberg atoms held in optical tweezer arrays represent currently one of the most advanced simulator platforms. They are particularly suited for the implementation and study of strongly interacting spin systems. In this talk I will present results on the coherent many-body dynamics in the so-called *facilitation regime*. The focus of my talk is on the understanding of the interplay between Rydberg excitations and lattice vibrations. Using both analytical arguments and numerical simulations, I will show how vibrations of the atoms around their local equilibrium positions can alter the dispersion relation of spin excitations or even leads to their spatial localization.
