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…

Energy diffusion in hard-point systems
L. Delfini, S. Denisov, S. Lepri +3
We investigate the diffusive properties of energy fluctuations in a one-dimensional diatomic chain of hard-point particles interacting through a square--well potential. The evoluti…
