Abstract
We show that Quantum-Monte-Carlo calculations of the dynamic structure factor of the isotropic spin-1/2 antiferromagnetic chain at intermediate temperatures corroborate a picture of diffusive spin dynamics at finite frequencies in the low-energy long wave-length limit and are in good agreement with recent predictions for this by J. Sirker, R. G. Pereira, and I. Affleck [arXiv:0906.1978v1].
