Localization in one-dimensional chains with Lévy-type disorder
Sepideh S. Zakeri, Stefano Lepri, Diederik S. Wiersma
We study Anderson localization of the classical lattice waves in a chain with mass impurities distributed randomly through a power-law relation with as the dista…
Coherent energy transport in classical nonlinear oscillators: an analogy with the Josephson effect
Simone Borlenghi, Stefano Iubini, Stefano Lepri +3
The standard approach to non-equilibrium thermodynamics describes transport in terms of generalised forces and coupled currents, a typical example being the Fourier law that relate…
Nonreciprocal wave scattering on nonlinear string-coupled oscillators
Stefano Lepri, Arkady Pikovsky
We study scattering of a periodic wave in a string on two lumped oscillators attached to it. The equations can be represented as a driven (by the incident wave) dissipative (due to…
Anomalous transmission and drifts in one-dimensional Levy structures
Piercesare Bernabó, Raffaella Burioni, Stefano Lepri +1
We study the transmission of random walkers through a finite-size inhomogeneous material with a quenched, long-range correlated distribution of scatterers. We focus on a finite one…
Boundary-induced instabilities in coupled oscillators
Stefano Iubini, Stefano Lepri, Roberto Livi +1
A novel class of nonequilibrium phase-transitions at zero temperature is found in chains of nonlinear oscillators.For two paradigmatic systems, the Hamiltonian XY model and the dis…
