Lieb-Robinson bounds for open quantum systems with long-ranged interactions

Journal of Physics A: Mathematical and Theoretical, Volume 52, No. 42, Article 424003, Year 2019

We state and prove four types of Lieb-Robinson bounds valid for many-body open quantum systems with power law decaying interactions undergoing out of equilibrium dynamics. We also provide an introductory and self-contained discussion of the setting and tools necessary to prove these results. The results found here apply to physical systems in which both long-ranged interactions and dissipation are present, as commonly encountered in certain quantum simulators, such as Rydberg systems or Coulomb crystals formed by ions.
