Finite Size Scaling of the Spin Stiffness of the Antiferromagnetic S=1/2 XXZ chain

Nicolas Laflorencie, Sylvain Capponi, Erik S. Sorensen

We study the finite size scaling of the spin stiffness for the one-dimensional s=1/2 quantum antiferromagnet as a function of the anisotropy parameter Delta.Previous Bethe ansatz r…
