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.

The effective temperature in a system with two heat baths of temperatures T1 and T2 attached may be outside of the interval [T1, T2]. See, e.g., M. Droz, Z. Rácz, and J. Schmidt, Phys. Rev. A 39:2141 (1989).

A. M. Tsvelik, Phys. Rev. B 42:779 (1990). The original motivation for studying the XXZ model with energy current was the interest in exactly solvable models with competing interactions. As a simplest competing interaction, the second integral of motion, j2, was added to the XXZ hamiltonian and j2 turns out to be the energy current operator.
