Description:
Author(s): Jean-Sébastien Caux, Hitoshi Konno, Mark Sorrell, and Robert Weston We consider the effects of interactions on spinon excitations in Heisenberg spin- 1/2 chains. We compute the exact two-spinon part of the longitudinal structure factor of the infinite chain in zero field for all values of anisotropy in the gapless antiferromagnetic regime, via an exact algebraic appr...
