We have demonstrated the coherent energy exchange in chains of Rydberg atoms resulting from their resonant dipole-dipole interaction. This interaction realizes the XY spin model and leads to the hopping a spin excitation from a site to another. We use this interaction to study elementary excitations in a dimerized spin chain featuring topological properties (Su-Schrieffer-Heeger model). We have observed the edge states in the topological condition. We probed the regime beyond the linear response by adding several excitations, which act as hard-core bosons .
With optical dipoles, we explore light scattering in one dimensional chains of atoms. This system realizes a dissipative spin model, which could find applications in quantum optics to generate optical non-linearities and non-classical states of light .
