Multiplicity of Stable Attractors in Disordered Neural Models
Raffaele Marino, Roberto Livi, Antonio Politi
We show how large-deviation statistics allows one to obtain reliable estimates of the multiplicity of stable fixed-points in a model of neural ordinary differential equations previ…
Anomalous transport in the Fermi-Pasta-Ulam-Tsingou model: a review and open problems
Stefano Lepri, Roberto Livi, Antonio Politi
This review provides an up-to-date account of energy transport in Fermi-Pasta-Ulam-Tsingou (FPUT) chains, a key testbed for nonequilibrium statistical physics. We discuss the trans…
Numerical analysis of heat transport in classical one-dimensional systems
Antonio Politi
Numerical studies of some unidimensional systems suggest that Fourier law is satisfied, where theory predicts a divergence of heat conductivity with the system size. Here, I revisi…
Nonequilibrium dynamics of a stochastic model of anomalous heat transport: numerical analysis
L. Delfini, S. Lepri, R. Livi +2
We study heat transport in a chain of harmonic oscillators with random elastic collisions between nearest-neighbours. The equations of motion of the covariance matrix are numerical…
Nonequilibrium dynamics of a stochastic model of anomalous heat transport
S. Lepri, C. Mejia-Monasterio, A. Politi
We study the dynamics of covariances in a chain of harmonic oscillators with conservative noise in contact with two stochastic Langevin heat baths. The noise amounts to random coll…
A stochastic model of anomalous heat transport: analytical solution of the steady state
Stefano Lepri, Carlos Mejia-Monasterio, Antonio Politi
We consider a one-dimensional harmonic crystal with conservative noise, in contact with two stochastic Langevin heat baths at different temperatures. The noise term consists of col…
