Information propagation in long-range quantum many-body systems

Marius Lemm, Carla Rubiliani, Israel Michael Sigal +1

We study general lattice bosons with long-range hopping and long-range interactions decaying as $|x-y{|}^{-\alpha }$ with $\alpha \in (d+2,2d+1)$. We find a linear light cone for the informatio…
