Laser spectroscopic probing of coexisting superfluid and insulating states of an atomic Bose–Hubbard system

A system of ultracold atoms in an optical lattice can be used as a quantum simulator for the Hubbard model with high controllability. Here, the authors report a laser spectroscopy study of an ytterbium ultracold bosonic gas across the weakly to strongly interacting regime.
