Dissipation-Enabled Operator-Norm Locality Bounds for Bose-Hubbard Hamiltonians
The paper investigates how local dissipation in bosonic lattice systems restores operator-norm Lieb–Robinson bounds, overcoming limitations where information speed grows with local particle density. By using localized loss to suppress high occupations, the authors establish moment-controlled locality and simulation bounds for the Bose-Hubbard model. This provides a way to achieve local channel approximation and quantitative thermodynamic limits without needing initial state assumptions.
