Transmission thresholds in time-periodically driven nonlinear disordered systems
Magnus Johansson, Georgios Kopidakis, Stefano Lepri +1
We study energy propagation in locally time-periodically driven disordered nonlinear chains. For frequencies inside the band of linear Anderson modes, three different regimes are o…
Heat wave propagation in a nonlinear chain
F. Piazza, S. Lepri
We investigate the propagation of temperature perturbations in an array of coupled nonlinear oscillators at finite temperature. We evaluate the response function at equilibrium and…
Nonequilibrium Invariant Measure under Heat Flow
L. Delfini, S. Lepri, R. Livi +1
We provide an explicit representation of the nonequilibrium invariant measure for a chain of harmonic oscillators with conservative noise in the presence of stationary heat flow. B…
Anomalous transport and relaxation in classical one-dimensional models
G. Basile, L. Delfini, S. Lepri +3
After reviewing the main features of anomalous energy transport in 1D systems, we report simulations performed with chains of noisy anharmonic oscillators. The stochastic terms are…
