Computing Nonequilibrium Transport from Short-Time Transients: From Lorentz Gas to Heat Conduction in One Dimensional Chains

Davide Carbone, Vincenzo Di Florio, Stefano Lepri +1

We test the Transient Time Correlation Function (TTCF) method to compute nonequilibrium transport coefficients, highlighting its conceptual and practical difference from the standa…

Dephasing-induced relaxation in tight-binding chains with linear and nonlinear defects

Debraj Das, Andrea Gambassi, Stefano Iubini +1

We investigate thermalization in a tight-binding chain with an on-site defect subject to local dephasing noise implemented as random phase kicks. For a single linear defect of stre…

Lax dynamics

Stefano Lepri

A novel approach is proposed to characterize the dynamics of perturbed many-body integrable systems. Focusing on the paradigmatic case of the Toda chain under non-integrable Hamilt…

Thermal transport in long-range interacting harmonic chains perturbed by long-range conservative noise

Francesco Andreucci, Stefano Lepri, Carlos Mejía-Monasterio +1

We study non-equilibrium properties of a chain of oscillators with both long-ranged harmonic interactions and long-range conservative noise that exchange momenta of particle pa…

Large-deviations approach to thermalization: the case of harmonic chains with conservative noise

Stefano Lepri

We investigate the possibility of characterizing the different thermalization pathways through a large-deviation approach. Specifically, we consider clean, disordered and quasi-per…

-symmetric ladders with a scattering core

Jennie D'Ambroise, Stefano Lepri, Boris A. Malomed +1

We consider a -symmetric chain (ladder-shaped) system governed by the discrete nonlinear Schrödinger equation where the cubic nonlinearity is carried solely by two ce…

Eigenstates and instabilities of chains with embedded defects

J. D'Ambroise, P. G. Kevrekidis, S. Lepri

We consider the eigenvalue problem for one-dimensional linear Schrödinger lattices (tight-binding) with an embedded few-sites linear or nonlinear, Hamiltonian or non-conservative d…

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…

Pattern formation and localization in the forced-damped FPU lattice

Ramaz Khomeriki, Stefano Lepri, Stefano Ruffo

We study spatial pattern formation and energy localization in the dynamics of an anharmonic chain with quadratic and quartic intersite potential subject to an optical, sinusoidally…
