Presence of energy flux in quantum spin chains: An experimental signature

Abstract

Using the XXZ model for the description of one-dimensional magnetic materials we show that an energy flux, j_E, produces a shift, dk (j_E)^0.5, in the characteristic wavenumber of the spin-spin correlations. We estimate dk for a realistic experimental setup and find that it is measurable in inelastic neutron scattering experiments.
