Cooling rate and glassy behavior in the Fermi--Pasta--Ulam system
Matteo Razza, Andrea Carati, Luigi Galgani
The authors numerically study how a Fermi‑Pasta‑Ulam chain cools when coupled to a gas whose temperature is lowered at a given rate, discovering that below a weak stochastic thresh…

Spectra as a classical phenomenon, and the Einstein classical program
Andrea Carati, Luigi Galgani, Fabrizio Gangemi
According to Born (\emph{Atomic Physics, page 103}), spectra are \emph{``quantum phenomena, which from a classical standpoint are perfectly unintelligible''}. However we illustrate…

A survey on rigorous results for the dynamics of periodic FPU chains
Dario Bambusi, Andrea Carati, Alberto Maiocchi
In this paper we review some analytic results on the dynamics of the FPU system. In the first part of the paper, having in mind that the FPU Hamiltonian and the Toda Hamiltonian ar…
