Analytical expressions for the transport coefficients of liquids based on the corrected Enskog theory have been used in order to determine the self-diffusion coefficient (D) for molecular liquids as a function of density and temperature. The liquids considered are those composed of linear...

Using the Navier-Stokes equations for classical monatomic fluids as a model, it is shown that propagation gaps can occur in sound dispersion curves. As in kinetic theory, these gaps arise when dissipative forces interfere strongly with elastic forces.

Some recent light scattering experiments on fast slow sound binary fluid mixtures are analyzed on the basis of a hard sphere model, introduced earlier. The association of fast and slow sound with the light and heavy component of the mixture, respectively, is confirmed by considering the...

In Lorentz Lattice Gases a point particle moves along the bonds of a lattice, whose lattice sites are occupied by randomly placed scatterers, which scatter the particle according to certain a priori given scattering rules. We consider here mainly the simplest case of a square lattice fully or...

We analyze some models of nonequilibrium systems proposed in the past decade which derive the laws of irreversible thermodynamics from deterministic dynamics. We find that these models do not posses the crucial property of local thermodynamic equilibrium, since they represent noninteracting...

The analogy between the line widths of light scattered by colloidal suspensions and neutrons scattered by simple fluids is discussed. Contrary to what is presented in the literature, this analogy - in particular the observed narrowing of the lines - is in both cases related to particle diffusion...

In the last 10 years, a number of “conventional fluctuation theorems” have been derived for systems with deterministic or stochastic dynamics, in a transient or in a non-equilibrium stationary state. These theorems gave explicit expressions for the ratio of the probability to find the system...

We consider nonequilibrium systems with complex dynamics in stationary states with large fluctuations of intensive quantities (e.g. the temperature, chemical potential or energy dissipation) on long time scales. Depending on the statistical properties of the fluctuations, we obtain different...

The analysis of transport coefficients based on the modified Enskog theory (MET), discussed in a previous publication, has been extended to include the self-diffusion coefficient (D) and the bulk viscosity coefficient (ηv). Specifically, calculated values according to the MET are compared with...

We derive a generalized version of the work fluctuation theorem for non-equilibrium systems with spatio-temporal temperature fluctuations. For χ2-distributed inverse temperature, we obtain a generalized fluctuation theorem based on q-exponentials, whereas for other temperature distributions...
