dc.description.abstractUltracold atoms in optical lattices provide a unique opportunity to study Bose-Hubbard physics. In this work we show that by considering a spatially varying on-site interaction it is possible to manipulate the motion of excitations above theMott phase in a Bose-Hubbard system. Specifically, we show that it is possible to “engineer” regimes where excitations will negatively refract, facilitating the construction of a flat lens.en
