Hubbard models and state preparation in an optical Lieb lattice
Hubbard models and state preparation in an optical Lieb lattice
Inspired by the growing interest in probing many-body phases in novel two-dimensional lattice geometries we investigate the properties of cold atoms as they could be observed in an optical Lieb lattice. We begin by computing Wannier functions localised at individual sites for a realistic experimental setup, and determining coefficients for …
