In my talk I will start with a review of our recent work on realizing a broad class of lattice spin-1/2 models with cold alkali atoms stored in optical or magnetic trap arrays. In particular, we exploit the strong angular dependence of van der Waals interactions between high angular momentum Rydberg states. Together with the possibility of designing step-like potentials we can implement Abelian gauge theories in a series of geometries, which could be demonstrated within state of the art experiments. The resulting energy scales of interactions compare well with typical temperatures and decoherence time-scales, making the exploration of exotic forms of quantum magnetism, including emergent gauge theories, compass models and quantum spin ice models, accessible within state-of-the-art experiments.
