Nonequilibrium phenomena in nonlinear lattices: from slow relaxation to anomalous transport
Stefano Iubini, Stefano Lepri, Roberto Livi +2
This Chapter contains an overview of the effects of nonlinear interactions in selected problems of non-equilibrium statistical mechanics. Most of the emphasis is put on open setups…
Localization transition in the Discrete Non-Linear Schrödinger Equation: ensembles inequivalence and negative temperatures
Giacomo Gradenigo, Stefano Iubini, Roberto Livi +1
We present a detailed account of a first-order localization transition in the Discrete Nonlinear Schrödinger Equation, where the localized phase is associated to the high energy re…
Coupled transport in a linear-stochastic Schrödinger Equation
Stefano Iubini
I study heat and norm transport in a one-dimensional lattice of linear Schrödinger oscillators with conservative stochastic perturbations. Its equilibrium properties are the same o…
Rate dependence of current and fluctuations in jump models with negative differential mobility
Gianluca Teza, Stefano Iubini, Marco Baiesi +2
Negative differential mobility is the phenomenon in which the velocity of a particle decreases when the force driving it increases. We study this phenomenon in Markov jump models w…
Equilibrium time-correlation functions of the long-range interacting Fermi-Pasta-Ulam model
Pierfrancesco Di Cintio, Stefano Iubini, Stefano Lepri +1
We present a numerical study of dynamical correlations (structure factors) of the long-range generalization of the Fermi-Pasta-Ulam oscillator chain, where the strength of the inte…
