Long persistence of localization in a disordered anharmonic chain beyond the atomic limit
Wojciech De Roeck, François Huveneers, Oskar A. ProÅniak
We establish rigorous bounds on the decorrelation time and thermal transport in the disordered Klein-Gordon chain with a quartic on-site potential, governed by a parameter . At…

Slow dissipation and spreading in disordered classical systems: A direct comparison between numerics and mathematical bounds
Wojciech De Roeck, François Huveneers, Oskar A. ProÅniak
We study the breakdown of Anderson localization in the one-dimensional nonlinear Klein-Gordon chain, a prototypical example of a disordered classical many-body system. A series of…
