Damage spreading and Lyapunov exponents in cellular automata
F. Bagnoli, R. Rechtman, S. Ruffo
Using the concept of the Boolean derivative we study damage spreading for one dimensional elementary cellular automata and define their maximal Lyapunov exponent. A random matrix a…
On the microcanonical solution of a system of globally coupled rotators
Mickael Antoni, Haye Hinrichsen, Stefano Ruffo
We study the Hamiltonian Mean Field (HMF) model, a system of fully coupled particles, in the microcanonical ensemble. We use the previously obtained free energy in the canonica…
Modular Transformations, Order-Chaos Transitions and Pseudo-Random Number Generation
Antonio Bonelli, Stefano Ruffo
Successive pairs of pseudo-random numbers generated by standard linear congruential transformations display ordered patterns of parallel lines. We study the ``ordered'' and ``chaot…
Hamiltonian Dynamics and the Phase Transition of the XY Model
Xavier Leoncini, Alberto D. Verga, Stefano Ruffo
A Hamiltonian dynamics is defined for the XY model by adding a kinetic energy term. Thermodynamical properties (total energy, magnetization, vorticity) derived from microcanonical…
Transmission and Scattering of a Lorentz Gas on a Slab
Hernan Larralde, Francois Leyvraz, Gustavo Martinez-Mekler +2
We perform numerical scattering experiments on a Lorentz array of disks centered on a triangular lattice with L columns and study its transmission and reflection properties. In the…
Chaos and Statistical Mechanics in the Hamiltonian Mean Field Model
Vito Latora, Andrea Rapisarda, Stefano Ruffo
We study the dynamical and statistical behavior of the Hamiltonian Mean Field (HMF) model in order to investigate the relation between microscopic chaos and phase transitions. HMF…
