Comment on Adjacent spin operator dynamical structure factor of the S=1/2 Heisenberg chain'

Abstract

We consider the paper Adjacent spin operator dynamical structure factor of the S=1/2 Heisenberg chain, by Klauser, Mossel and Caux (2012 J.Stat.Mech.P03012) to be a new and important step in the numerical analysis of the correlation functions of quantum spin chains. The correlation functions considered in this paper were not previously computed, their analytical study is extremely complicated and the numerical results can be used for comparison with experiments. © 2012 IOP Publishing Ltd and SISSA Medialab srl.
