Normal Heat Conductivity in a strongly pinned chain of anharmonic oscillators
R. Lefevere, A. Schenkel
We consider a chain of coupled and strongly pinned anharmonic oscillators subject to a non-equilibrium random forcing. Assuming that the stationary state is approximately Gaussian,…

Perturbative analysis of anharmonic chains of oscillators out of equilibrium
R. Lefevere, A. Schenkel
We compute the first-order correction to the correlation functions of the stationary state of a stochastically forced harmonic chain out of equilibrium when a small on-site anharmo…
