Description
We discuss a one-dimensional model of a vibrating rigid rod, in and out of equilibrium. We study stationary states when the system is subject to temperature gradients, which is the nonequilibrium scenario, as compared to constant temperature for the equilibrium situations. While some thermomechanical properties remain substantially unchanged comparing in and out of equilibrium situations, the energy of competence of the first few modes is substantially augmented, compared to its putative equipartition among the modes. The numerical model is composed of particles in the bulk which interact purely Newtonianly, thus indicating a genuine effect. The theoretical model is only tentative, and based on probabilistic ansatzes.
