Long-range interacting quantum systems

Webis obtained in generic long-range interacting systems under the condition of α > 2Dþ1. As related work, in one-dimensional two-body interacting systems, the long-range Lieb-Robinson bound has been proved very recently in the form of k½O iðtÞ;O jk ≲t=Rfor α > 3 [112], which gives a nontrivial upper bound up to the time t ¼ OðRÞ.
