Path-Integral Calculation of the Second Dielectric and Refractivity Virial Coefficients of Helium, Neon, and Argon. [PDF]

open access: yesJ Res Natl Inst Stand Technol, 2020
We present a method to calculate dielectric and refractivity virial coefficients using the path-integral Monte Carlo formulation of quantum statistical mechanics and validate it by comparing our results with equivalent calculations in the literature and ...

Second order virial coefficients from phase diagrams

open access: yes, 2020
The prediction of phase separation is essential to understand and control the properties of food systems. In this work, an existing theoretical model for describing phase separation between binary mixtures of hydrocolloids, using a virial approach up to ...

Intermolecular model potentials and virial coefficients from acoustic data

open access: yesJournal of Applied Sciences and Environmental Management, 2018
A simple method is presented for the determination of model two- and three-body intermolecular potentials from acoustic data. The method is applied to argon, nitrogen, methane, ethane and propane.

On extrapolation of virial coefficients of hard spheres

open access: yesCondensed Matter Physics, 2012
Several methods of extrapolating the virial coefficients, including those proposed in this work, are discussed. The methods are demonstrated on predicting higher virial coefficients of one-component hard spheres.

Virial coefficients of one-dimensional and two-dimensional Fermi gases by stochastic methods and a semiclassical lattice approximation [PDF]

open access: yesPhysical Review A, 2018
We map out the interaction effects on the first six virial coefficients of one-dimensional Fermi gases with zero-range attractive and repulsive interactions, and the first four virial coefficients of the two-dimensional analog with attractive ...

DEFORMED GAS OF p, q-BOSONS: VIRIAL EXPANSION AND VIRIAL COEFFICIENTS [PDF]

open access: yesModern Physics Letters B, 2012
In the study of many-particle systems both the interaction of particles can be essential and such feature as their internal (composite) structure. To describe these aspects, the theory of deformed oscillators is very efficient. Viewing the particles as p, q-deformed bosons, in the corresponding p, q-Bose gas model we obtain in explicit form virial ...

Computation of high-order virial coefficients in high-dimensional hard-sphere fluids by Mayer sampling

open access: yes, 2014
The Mayer sampling method was used to compute the virial coefficients of high-dimensional hard-sphere fluids. The first 64 virial coefficients for dimensions 12 < D ⩽ 100 were obtained to high precision, and several lower dimensional virial coefficients ...
