Geometric approach to Hamiltonian dynamics and statistical mechanics
Lapo Casetti, Marco Pettini, E. G. D. Cohen
This paper is a review of results which have been recently obtained by applying mathematical concepts drawn, in particular, from differential geometry and topology, to the physics…
Note on the Kaplan-Yorke dimension and linear transport coefficients
Denis J. Evans, E. G. D. Cohen, Debra J. Searles +1
A number of relations between the Kaplan-Yorke dimension, phase space contraction, transport coefficients and the maximal Lyapunov exponents are given for dissipative thermostatted…
Spatial Particle Condensation for an Exclusion Process on a Ring
N. Rajewsky, T. Sasamoto, E. R. Speer
We study the stationary state of a simple exclusion process on a ring which was recently introduced by Arndt {\it et al} [J. Phys. A {\bf 31} (1998) L45;cond-mat/9809123]. This mod…
Gibbs entropy and irreversible thermodynamics
L. Rondoni, E. G. D. Cohen
Recently a number of approaches has been developed to connect the microscopic dynamics of particle systems to the macroscopic properties of systems in nonequilibrium stationary sta…
Propagation and organization in lattice random media
Patrick Grosfils, Jean Pierre Boon, E. G. D. Cohen +1
We show that a signal can propagate in a particular direction through a model random medium regardless of the precise state of the medium. As a prototype, we consider a point parti…
