The Fermi-Pasta-Ulam problem revisited: stochasticity thresholds in nonlinear Hamiltonian systems
Lapo Casetti, Monica Cerruti-Sola, Marco Pettini +1
The Fermi-Pasta-Ulam -model of harmonic oscillators with cubic anharmonic interactions is studied from a statistical mechanical point of view. Systems of N= 32 to 128 oscillator…
Scaling of Particle Trajectories on a Lattice II: The Critical Region
Meng-she Cao, E. G. D. Cohen
The scaling behavior of the closed trajectories of a moving particle generated by randomly placed rotators or mirrors on a square or triangular lattice in the critical region are i…
Scaling of Particle Trajectories on a Lattice I: Critical Behavior
Meng-she Cao, E. G. D. Cohen
The scaling behavior of the closed trajectories of a moving particle generated by randomly placed rotators or mirrors on a square or triangular lattice is studied numerically. For…
Boltzmann and Statistical Mechanics
E. G. D. Cohen
Lecture given at the International Meeting ``Boltzmann's Legacy - 150 Years after his Birth'', organized by the Accademia Nazionale dei Lincei, 25 - 28 May 1994, in Rome, to be pub…
Viscosity of Colloidal Suspensions
R. Verberg, I. M. de Schepper, E. G. D. Cohen
Simple expressions are given for the Newtonian viscosity as well as the viscoelastic behavior of the viscosity of neutral monodisperse hard sphere colloidal suspe…
Lyapunov Exponents from Kinetic Theory for a Dilute, Field-driven Lorentz Gas
H. van Beijeren, J. R. Dorfman, E. G. D. Cohen +2
Positive and negative Lyapunov exponents for a dilute, random, two-dimensional Lorentz gas in an applied field, , in a steady state at constant energy are computed to orde…
