DESCRIPTION:Speaker: Johannes Feldmeier\nhosted by Maksym Serbyn and Jean Y
 ves-Desaules\nAbstract: Neutral atom arrays driven into Rydberg states are
  a promising approach for realizing programmable quantum systems\, where s
 trong interactions associated with Rydberg blockade allow for simulation o
 f complex spin models. In this talk\, I will discuss a Floquet engineering
  technique that extends the capabilities of Rydberg quantum simulators and
  enables control over new forms of interactions. Our approach is based on 
 time-dependent modulation of Rydberg laser detuning and leverages controll
 ed deviations from periodic many-body trajectories as a resource for opera
 tor spreading. Such time-evolved operators provide a basis for engineering
  effective Hamiltonians with strong\, non-perturbative multi-body interact
 ions and we develop an optimization procedure for the time-dependent detun
 ing in order to realize specific many-body models. As applications\, we sh
 ow how to engineer spin chains that dynamically generate large-scale multi
 -partite entanglement from simple initial states\, and how to simulate dyn
 amics of certain two-dimensional lattice gauge theories in previously inac
 cessible regimes. I will discuss a first experimental implementation of ou
 r approach on a Rydberg quantum simulator and give an outlook on promising
  future directions.
