VIRIAL EXPANSION OF THE NUCLEAR EQUATION OF STATE [PDF]
We study the equation of state (EOS) of nuclear matter as function of density. We expand the energy per particle (E/A) of symmetric infinite nuclear matter in powers of the density to take into account 2, 3, …, N-body forces. New EOS are proposed by fitting ground state properties of nuclear matter (binding energy, compressibility and pressure) and ...

On the equivalence between the energy and virial routes to the equation of state of hard-sphere fluids [PDF]
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.

Infall near clusters of galaxies: comparing gas and dark matter velocity profiles [PDF]
We consider the dynamics in and near galaxy clusters. Gas, dark matter and galaxies are presently falling into the clusters between approximately 1 and 5 virial radii.

Equation of state for five-dimensional hyperspheres from the chemical-potential route [PDF]
We use the Percus-Yevick approach in the chemical-potential route to evaluate the equation of state of hard hyperspheres in five dimensions. The evaluation requires the derivation of an analytical expression for the contact value of the pair distribution

Virial expansions and augmented van der Waals approach: Application to Lennard-Jones-like Yukawa fluid [PDF]
We argue that recently proposed [Melnyk et al., Fluid Phase Equilibr., 2009, Vol. 279, 1] a criterion to split the pair interaction energy into two parts, one of which is forced to be responsible the most accurate as possible for excluded volume energy ...

Transport theory with nonlocal corrections [PDF]
A kinetic equation which combines the quasiparticle drift of Landau's equation with a dissipation governed by a nonlocal and noninstant scattering integral in the spirit of Snider's equation for gases is derived.

Substrate concentration dependence of the diffusion-controlled steady-state rate constant [PDF]
The Smoluchowski approach to diffusion-controlled reactions is generalized to interacting substrate particles by including the osmotic pressure and hydrodynamic interactions of the nonideal particles in the Smoluchoswki equation within a local-density ...

Cluster Formation and The Virial Equation of State of Low-Density Nuclear Matter
We present the virial equation of state of low-density nuclear matter composed of neutrons, protons and alpha particles. The virial equation of state is model-independent, and therefore sets a benchmark for all nuclear equations of state at low densities.
