On Lieb–Robinson Bounds for the Bose–Hubbard Model

We consider the dynamics of the Bose–Hubbard model on general lattices and prove a Lieb–Robinson bound for observables whose supports are separated by an initially almost particle-free region. We further obtain a maximal velocity bound for particle transport through an initially empty region which a...
