Notes: Abstract Using the XXZ model for the description of one-dimensional magnetic materials we show that an energy flux, j E, produces a shift, δk∼ $$\sqrt {j_E } $$ , in the characteristic wavenumber of the spin-spin correlations. We estimate δk for a realistic experimental setup and find that it is measurable in inelastic neutron scattering experiments.
