Chaos and Anderson Localisation in Disordered Classical Chains: Hertzian vs FPUT models

A. Ngapasare, G. Theocharis, O. Richoux +2

We numerically investigate the dynamics of an one-dimensional disordered lattice using the Hertzian model, describing a granular chain, and the $\alpha +\beta$ Fermi-Pasta-Ulam-Tsingou model…
