Magnetization and energy relaxation in the 1D XXZ Heisenberg model — •Xenophon Zotos^1,2 and Alexandros Pavlis¹ — ¹Physics Department, University of Crete, Greece — ²Leibnitz/IFW Dresden, Germany

We study spin and energy relaxation by the recently proposed Generalized Hydrodynamics approach (GHD) in the linear response regime. We derive a further formulation of the corresponding Drude weights from the finite wave-vector relaxation. Furthermore we analyze the dynamic structure factors in the low temperature regime and compare them to existing results in the literature.
