Abstract

Using the XXZ model for the description of one-dimensional magnetic materials we show that an energy flux, jE, produces a shift, δk ∼ radic;jE, 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.
