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. In our Web5 de jan. de 2024 · body quantum systems. In this Letter, we consider the MIP in long-range interacting systems to understand the mechanism more deeply. Here, long-range interaction means that the ampli-tude of interaction decays as r−α, where r is the distance between particles (see also Ref. [24]). As conceptually
