• Abstract: Cold Rydberg atoms trapped in an array of optical tweezers can be manipulated using laser light. We investigate the fate of out-of-equilibrium quantum dynamics in a model of Rydberg atoms arranged in a square ladder geometry within the strong blockade regime, with a detuning profile staggered along the longer direction. As the staggering strength is tuned, the model exhibits a wide class of dynamical phenomena, ranging from quantum many-body scars, integrability-induced slow dynamics and approximate Krylov fractures. Furthermore, by leveraging the chiral nature of the spectrum, we design Floquet protocols which result in dynamical signatures reminiscent of discrete-time-crystalline order and exact Floquet-flat-bands.
