The fourth virial coefficient for hard spheres in even dimension
Ignacio Urrutia
The fourth virial coefficient is calculated exactly for a fluid of hard spheres in even dimensions. For this purpose the complete star cluster integral is expressed as the sum of t…
Generalization of the Wall Theorem to Out-of-equilibrium Conditions
Ignacio Urrutia, Ivan Paganini, Claudio Pastorino
The well-known Wall theorem states a simple and precise relation among temperature, pressure and density of a fluid at contact with a confining hard wall in thermodynamic equilibri…
Bending and Gaussian rigidities of confined soft spheres from second-order virial series
Ignacio Urrutia
We use virial series to study the equilibrium properties of confined soft-spheres fluids interacting through the inverse-power potentials. The confinement is induced by hard walls…
Virial series for inhomogeneous fluids applied to the Lennard-Jones wall-fluid surface tension at planar and curved walls
Ignacio Urrutia, Iván Paganini
We formulate a straightforward scheme of statistical mechanics for inhomogeneous systems that includes the virial series in powers of the activity for the grand free energy and den…
Fluids confined in wedges and by edges: virial series for the line-thermodynamic properties of hard spheres
Ignacio Urrutia
This work is devoted to analyze the relation between the thermodynamic properties of a confined fluid and the shape of its confining vessel. Recently, new insights in this topic we…
Fluids confined in wedges and by edges: From cluster integrals to thermodynamic properties referred to different regions
Ignacio Urrutia
Recently, new insights in the relation between the geometry of the vessel that confines a fluid and its thermodynamic properties were traced through the study of cluster integrals…
