Cooling rate and glassy behavior in the Fermi--Pasta--Ulam system
Matteo Razza, Andrea Carati, Luigi Galgani
In this work, we numerically studied the cooling process of a Fermi--Pasta--Ulam system, which occurs when the FPU system is placed in contact with a gas whose temperature is r…
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 dynamical approach to the - displacive transition of quartz
Andrea Carati, Fabrizio Gangemi, Roberto Gangemi +1
General features of the transition of quartz are investigated. Molecular dynamics methods are mainly used, an analytic treatment being deferred to a work in preparation. A ba…
Tsallis distributions, their relaxations and the relation , in the dynamical fluctuations of a classical model of a crystal
Andrea Carati, Luigi Galgani, Fabrizio Gangemi +1
We report the results of a numerical investigation, performed in the frame of dynamical systems' theory, for a realistic model of a ionic crystal for which, due to the presence of…
Chemical bond by Newtonian trajectories in the ion
Andrea Carati, Luigi Galgani, Fabrizio Gangemi +1
According to the correspondence principle, classical mechanics and quantum mechanics agree in the semiclassical limit, although presently it has become more and more clear how intr…
Approach to equilibrium via Tsallis distributions in a realistic ionic--crystal model and in the FPU model
Andrea Carati, Luigi Galgani, Fabrizio Gangemi +1
In Statistical Mechanics, Tsallis distributions were apparently conceived in connection with systems presenting long--range interactions. In fact, they were observed in numerical c…
