Lieb-Robinson bounds and out-of-time order correlators in a long-range spin chain
Lieb-Robinson bounds quantify the maximal speed of information spreading in nonrelativistic quantum systems. We discuss the relation of Lieb-Robinson bounds to out-of-time order correlators, which correspond to different norms of commutators C(r,t)=[A_{i}(t),B_{i+r}] of local operators. Using an exa...
