Spin diffusion from an inhomogeneous quench in an integrable system

The anisotropic Heisenberg model is integrable, possessing a macroscopic number of conserved quantities that constrain the many-body dynamics. Here the authors show numerically that, despite its integrability, it can exhibit diffusive and, at the isotropic point, super-diffusive behaviour.
