We propose, as a generalization of an idea of Ruelle's to describe turbulent fluid flow, a chaotic hypothesis for reversible dissipative many-particle systems in nonequilibrium stationary states in general. This implies an extension of the zeroth law of thermodynamics to nonequilibrium states and it leads to the identification of a unique distribution μ describing the asymptotic properties of the time evolution of the system for initial data randomly chosen with respect to a uniform…

Heat and fluctuations from order to chaos
Abstract.The Heat theorem reveals the second law of equilibrium Thermodynamics (i.e. existence of Entropy) as a manifestation of a general property of Hamiltonian Mechanics and of the Ergodic
Smooth Dynamics and New Theoretical Ideas in Nonequilibrium Statistical Mechanics
This paper reviews various applications of the theory of smooth dynamical systems to conceptual problems of nonequilibrium statistical mecanics. We adopt a new point of view which has emerged
Fluctuations in two-dimensional reversibly damped turbulence
Gallavotti proposed an equivalence principle in hydrodynamics, which states that forced-damped fluids can be equally well represented by means of the Navier-Stokes equations and by means of
Fluctuation Relations and Nonequilibrium Response for Chaotic Dissipative Dynamics
In a recent paper [Colangeli and Rondoni, Physica D 241:681, 2011] it was argued that the Fluctuation Relation for the phase space contraction rate Λ could suitably be extended to non-reversible
Dynamical systems of eternal inflation: a possible solution to the problems of entropy, measure, observables and initial conditions
There are two main approaches to non-equlibrium statistical mechanics: one using stochastic processes and the other using dynamical systems. To model the dynamics during inflation one usually adopts
Nonequilibrium Steady State Thermodynamics and Fluctuations for Stochastic Systems
Abstract We use the work done on and the heat removed from a system to maintain it in a nonequilibrium steady state for a thermodynamic-like description of such a system as well as of its

TLDR
Finite-time averages of the phase-space contraction rate have nontrivial fluctuations which are complementary to the usual fluctuation theorem for nonequilibrium stationary states and appropriate to constrained equilibrium states and show that these fluctuations are distributed according to a Gaussian curve for long enough times.

We study nonequilibrium steady states in the Lorentz gas of periodic scatterers when an electric external field is applied and the particle kinetic energy is held fixed by a “thermostat” constructed

Nonequilibrium systems in thermodynamic steady states can be studied by computer simulation, and the calculated transport coefficients are in agreement with results obtained by equilibrium methods.

Physical and numerical experiments show that deterministic noise, or chaos, is ubiquitous. While a good understanding of the onset of chaos has been achieved, using as a mathematical tool the
Stationary shear flow in boundary driven Hamiltonian systems.
TLDR
The average rates of phase space volume contraction and macroscopic entropy production are shown to be equal for stationary hydrodynamic shear flows, i.e. when the velocity distribution of particles incident on the walls is a local Maxwellian.
Dynamical Ensembles in Nonequilibrium Statistical Mechanics.
TLDR
This presents the first test of the Ruelle principle on a many particle system far from equilibrium, and a specific prediction, obtained without the need to construct explicitly the SRB itself, is shown to be in agreement with a recent computer experiment on a strongly sheared fluid.
Resolution of Loschmidt's paradox: The origin of irreversible behavior in reversible atomistic dynamics.
TLDR
Nosromane-bar mechanics provides a link between computer simulations of nonequilibrium processes and real-world experiments and shows that irreversible behavior consistent with the second law of thermodynamics arises from completely reversible microscopic motion.

Probability of second law violations in shearing steady states.
TLDR
An expression for the probability of fluctuations in the shear stress of a fluid in a nonequilibrium steady state far from equilibrium is given and a formula for the ratio that, for a finite time, theShear stress reverse sign is violating the second law of thermodynamics.
