Weak and strong chaos in FPU models and beyond
Marco Pettini, Lapo Casetti, Monica Cerruti-Sola +2
We briefly review some of the most relevant results that our group obtained in the past, while investigating the dynamics of the Fermi-Pasta-Ulam (FPU) models. A first result is th…
Topology and phase transitions: from an exactly solvable model to a relation between topology and thermodynamics
Luca Angelani, Lapo Casetti, Marco Pettini +2
The elsewhere surmised topological origin of phase transitions is given here new important evidence through the analytic study of an exactly solvable model for which both topology…
Tailoring Phase Space : A Way to Control Hamiltonian Transport
Guido Ciraolo, Cristel Chandre, Ricardo Lima +3
We present a method to control transport in Hamiltonian systems. We provide an algorithm - based on a perturbation of the original Hamiltonian localized in phase space - to design…
Controlling chaos in area-preserving maps
Cristel Chandre, Michel Vittot, Yves Elskens +2
We describe a method of control of chaos that occurs in area-preserving maps. This method is based on small modifications of the original map by addition of a small control term. W…
Controlling chaotic transport in a Hamiltonian model of interest to magnetized plasmas
Guido Ciraolo, Cristel Chandre, Ricardo Lima +4
We present a technique to control chaos in Hamiltonian systems which are close to integrable. By adding a small and simple control term to the perturbation, the system becomes more…
