Description:
Author(s): Marko Žnidarič We analytically and numerically study spin transport in a one-dimensional Heisenberg model in linear-response regime at infinite temperature. It is shown that as the anisotropy parameter Δ is varied spin transport changes from ballistic for Δ 〈1 to anomalous at the isotropic point Δ =1 , to diffusiv... [Phys. Rev.
