Nearly-linear light cones in long-range interacting quantum systems
Michael Foss-Feig, Zhe-Xuan Gong, Charles W. Clark +1
In non-relativistic quantum theories with short-range Hamiltonians, a velocity can be chosen such that the influence of any local perturbation is approximately confined to with…
Non-local propagation of correlations in long-range interacting quantum systems
Philip Richerme, Zhe-Xuan Gong, Aaron Lee +6
The maximum speed with which information can propagate in a quantum many-body system directly affects how quickly disparate parts of the system can become correlated and how diffic…
Persistence of locality in systems with power-law interactions
Zhe-Xuan Gong, Michael Foss-Feig, Spyridon Michalakis +1
Motivated by recent experiments with ultra-cold matter, we derive a new bound on the propagation of information in -dimensional lattice models exhibiting interactions wi…
