Normal heat conductivity in a periodic chain of anharmonic oscillators
We consider a periodic chain of coupled and pinned anharmonic oscillators subject to a nonequilibrium random forcing. Assuming that the six-point correlation functions of the stationary state factorize in terms of the two-point correlation functions, we show that the heat current going through the system is consistent with Fourier law and that the conductivity behaves as κ ∼ 1 λ2T2 where λ is t...
متن کاملThermal conductivity for a chain of anharmonic oscillators perturbed by a conservative noise
We consider d-dimensional chains of (an)harmonic oscillators we perturb by a noise conserving energy or energy and momentum. We review the thermal conduction properties we obtained for these systems ([8], [1], [6], [2]) and conclude by several open questions.
متن کاملNon-Equilibrium Statistical Mechanics of Strongly Anharmonic Chains of Oscillators
We study the model of a strongly non-linear chain of particles coupled to two heat baths at different temperatures. Our main result is the existence and uniqueness of a stationary state at all temperatures. This result extends those of Eckmann, Pillet, Rey-Bellet [EPR99a,EPR99b] to potentials with essentially arbitrary growth at infinity. This extension is possible by introducing a stronger ver...
متن کاملMacroscopic energy diffusion for a chain of anharmonic oscillators
We study the energy diffusion in a chain of anharmonic oscillators where the Hamiltonian dynamics is perturbed by a local energy conserving noise. We prove that under diffusive rescaling of space-time, energy fluctuations diffuse and evolve following an infinite dimensional linear stochastic differential equation driven by the linearized heat equation. We also give variational expressions for t...
متن کاملBreathers in strongly anharmonic lattices.
We present and study a family of finite amplitude breathers on a genuinely anharmonic Klein-Gordon lattice embedded in a nonlinear site potential. The direct numerical simulations are supported by a quasilinear Schrodinger equation (QLS) derived by averaging out the fast oscillations assuming small, albeit finite, amplitude vibrations. The genuinely anharmonic interlattice forces induce breathe...
