Contact values of the particle-particle and wall-particle correlation functions in a hard-sphere polydisperse fluid
A. Santos, S. B. Yuste, M. Lopez de Haro
The contact values of the radial distribution functions of a fluid of (additive) hard spheres with a given size distribution are considered. A ``universality'' ass…
Seven views on approximate convexity and the geometry of K-spaces
Felix Cabello Sanchez, Jesus M. F. Castillo, Pier Luigi Papini
As in Hokusai's series of paintings "Thirty six views of mount Fuji" in which mount Fuji's is sometimes scarcely visible, the central topic of this paper is the geometry of -spa…
On the equivalence between the energy and virial routes to the equation of state of hard-sphere fluids
Andres Santos
The energy route to the equation of state of hard-sphere fluids is ill-defined since the internal energy is just that of an ideal gas and thus it is independent of density. It is s…
Structure of penetrable-rod fluids: Exact properties and comparison between Monte Carlo simulations and two analytic theories
Alexandr Malijevsky, Andres Santos
Bounded potentials are good models to represent the effective two-body interaction in some colloidal systems, such as dilute solutions of polymer chains in good solvents. The simpl…
Uniform shear flow in dissipative gases. Computer simulations of inelastic hard spheres and (frictional) elastic hard spheres
A. Astillero, A. Santos
In the preceding paper (cond-mat/0405252), we have conjectured that the main transport properties of a dilute gas of inelastic hard spheres (IHS) can be satisfactorily captured by…
Lightlike simultaneity, comoving observers and distances in general relativity
V. J. Bolós
We state a condition for an observer to be comoving with another observer in general relativity, based on the concept of lightlike simultaneity. Taking into account this condition,…
