Beschreibung
The competition of different length and energy scales in quantum many-body systems leads to various novel phenomena, including the emergence of correlated dynamics or non-local order. "Rydberg dressing", off-resonant optical coupling of an atomic ground state to a Rydberg state, enables to engineer long-range interactions on a micrometer scale, making it a powerful tool for studying correlated dynamics in lattice-based atomic quantum simulators. In our experiment, we leverage this tunability to realize a one-dimensional extended Bose Hubbard model for 87Rb atoms trapped in optical lattices. Unlike before, we enter the itinerant regime by applying stroboscopic dressing, reducing collective losses by two orders of magnitude. Operating at either low or high filling, we study the correlated out-of-equilibrium dynamics of extended-range repulsively-bound pair states or the near equilibrium density ordering when applying adiabatic ramps. Our findings pave the way to study itinerant, coupled ladder systems, and spin-breaking in stationary spin chains.
